08.0 Canyoneering Terminology & Things You’ll Hear in a Canyon
If you are going to spend time around canyoneers, you are going to hear a whole lot of words that sound made up.
Canyoneering has its own vocabulary because the terrain, rope systems, water, and problem-solving are unusually specific.
This section is a glossary of words, phrases, slang, abbreviations, and inside jokes commonly used in canyoneering. Some are formal technical terms. Others are simply the words canyon people use because saying the full version every time gets old very quickly.
I have also left some opinions and humor in here on purpose. Learning the language is part of learning the culture—and it makes a long glossary a lot less painful to read.
08.1 Can You Translate This?
“The beta says the keeper pothole is LDC below the drop-in, but the anchor is marginal and the pull is ugly.”
If that already makes perfect sense, congratulations—you are probably already one of us. If it sounds like another language, this module is exactly where you should be.
08.2 What Will You Run Into
Anchors and rigging. Rope and rappel commands. Movement and sequencing. Water and potholes. Beta, route-finding, and canyon directions. And finally, the strange little phrases that make perfect sense only after you have spent enough time in canyons.
Do not try to memorize all of it. The goal is recognition. Learn enough that when somebody says “LDC,” “rig it blocked,” or “that pothole is keeper-ish,” you know what they are talking about—or at least know what to look up.
08.3 Brett’s Opinion
Half the fun of a sport is learning the language that comes with it. The other half is not sounding like a complete noob when somebody starts speaking fluent canyon.
08.4 Canyon Terminology A-Z
The glossary
Do not try to memorize every term at once. Learn the language you are most likely to hear, then come back whenever somebody says something that makes you think, “Wait…what does that mean?”
A
Abseil — A non-U.S. term for what most Americans call rappelling. It comes from German for “down rope.” Same thing, different accent. If someone from Europe says they’re going to abseil, they are just going down the rope.
Advanced Canyon / Class 4 Canyon — In the ACA Canyon Rating System, Class 4 is advanced-expert terrain. It may include difficult or exposed climbing/downclimbing, high stemming or bridging, direct aid, multi-pitch rappels, complex rope work such as guided rappels, deviations or rebelays, obscure natural anchors, and advanced problem-solving or anchor-building.
Anchor — The point or system your rope is attached to so you can descend safely. This might be a tree, boulder, chockstone, bolt, sandtrap, deadman, pinch point, log, or in some cases a meat anchor using a person.
Anchor Extension — Extending anchor material out toward or over the edge so the rope runs cleaner, avoids sawing through sandstone, and reduces rope drag. Done right, it protects both the anchor and the rope. Done poorly, it creates a whole new problem.
Anchor Material — The stuff used to build, rebuild, or improve an anchor: webbing, cord, rapides, quick links, chain, etc. If someone says, “Can we farm anchor material from up-canyon?” that means the current day has already become more interesting than planned.
Approach — The hike from the trailhead to the canyon. Some approaches are short. Others are a full-blown event before the canyon even starts.
Artificial Anchor — A placed or constructed anchor, such as a bolt or buried deadman. Terminology varies between instructors. A toggle is a rigging or retrieval tool; the tree, rock, or other feature supporting that system is the anchor.
Ascend / Ascending — Climbing up a rope using specialized gear and technique. Most people love rappelling right up until they realize that ascending is the tax you pay when a rope gets stuck or a plan changes.
ATC / ATC-XP — A rappel device made by Black Diamond. The XP version has “teeth” for additional friction. It can work in some canyon situations, but many canyoneers prefer canyon-specific devices that allow more friction options and better control during long or variable rappels. Being replaced as the “de facto” to devices such as the SQWUREL and CRITR.
ATS — A rappel device made by Sterling and one of the canyon-specific devices that many canyoneers have used because it offers more flexibility (more horns to add friction to) than a standard climbing ATC.
Autoblock / self-belay — A friction-hitch backup used in some rappel systems. Placement and compatibility matter: a hitch can fail to grip, jam, or reach the descender. Becoming stuck on rope in flowing water can be fatal. Use only a configuration you have learned and tested with appropriate instruction.
B
Belay — A safety method that uses rope friction, a device, or a person managing the rope to protect someone on rappel or while climbing. In canyon talk, a fireman’s belay is the classic bottom belay where the person below pulls down on the rope to stop or slow the rappeller if needed.
Belay Loop — A primary load-bearing connection point on many modern climbing/canyoneering harnesses. Rappel and belay devices are commonly connected here when the harness manufacturer specifies it.
Belayer — The person giving the belay.
Bend — In rope terminology, a bend is a knot used to join two ropes or two pieces of webbing together. People casually call every rope knot a “knot,” but technically, a bend has a specific job.
Beta — Information about a canyon or route provided by previous descending parties. Route details, anchor condition, water level, approach notes, access issues, pothole status, rope lengths, or whether the canyon is currently “pleasantly wet” or “suspiciously miserable” — that is all beta. Treat beta as useful, but not the ultimate source. Canyons change constantly.
BFR / BFT — Slang for Big Freaking Rock and Big Freaking Tree — or the less family-friendly versions you will absolutely hear in the wild. The point is simple: very large natural anchors.
Bight — A curved section of rope used while tying a knot. Not the end of the rope. Not exactly the same thing as a loop.
Biner / Carabiner — Same thing. “Biner” is just shorthand because four syllables is a lot when you are standing at an anchor yelling over wind or moving water.
Biner Block — A rigging method that uses a carabiner and knot to block the rope at the anchor so the rappel is done on one side and the rope can later be retrieved. Very useful. Also dangerous if rigged incorrectly.
Bivy / Bivouac — An unplanned or minimalist overnight. Sometimes this means you intentionally carried lightweight emergency sleep gear. Sometimes it means the canyon chose for you. If someone says, “Plan for a bivy,” that is your hint they are not expecting a quick little afternoon outing.
Blocked Rappel — A rappel setup where the rope is blocked at the anchor so the canyoneer descends on a single strand. This is common in retrievable systems and guided rappels.
Bolt — A fixed anchor installed in drilled rock, usually with a hanger attached. Just because you see a bolt does not automatically mean it is safe. Check it. Every time.
Bolt Kit — The gear used to place bolts, usually including hardware, hangers, and a drill system. In canyoneering, bolting is often treated as a last-resort or ethics-heavy topic, not a default.
Bolt Wars — Community arguments over when bolts are acceptable, when they are overused, and whether someone has “improved” a canyon in ways others strongly disagree with. It sounds silly until you realize access, safety, ethics, and style are all wrapped into it.
Bottom Capture — A person below assists or receives the rappeller at the bottom of a drop, especially when the landing is awkward, slippery, in flow, or immediately transitions into another obstacle.
Boulder — A large rock. Sometimes useful as an anchor. Sometimes an obstacle. Sometimes both.
Brake Hand — The hand controlling the rope below the rappel device. This hand controls descent speed. This is the hand you never ever let go when rappelling.
Bridging — A movement technique where you place hands on one wall and feet on the opposite wall and move along the canyon using opposing pressure. It often looks graceful when skilled people do it and much less graceful when the rest of us do it.
C
Cairn — A stack of rocks used as a marker. Sometimes helpful. Often overused.
Candition.com — A crowd-sourced canyon-conditions website. The name combines “canyon” and “condition,” which is annoyingly clever. It can be useful for recent reports, but reports are snapshots.
Canyon — A deep valley or drainage carved by water. Some are wide and friendly. Some are narrow and very personal.
Canyon Left / Canyon Right — Same directional idea as LDC and RDC. Unless otherwise stated, directions are usually given as if you are facing down canyon.
Canyon Rating System — In North America, a widely used system is the ACA Canyon Rating System, which combines a technical class, a water rating, an optional time/commitment grade, and an optional risk/seriousness suffix such as R, X, or XX. Conditions, group skill, water, weather, and canyon changes still matter.
Canyoneer — A person who explores and descends technical canyons.
Canyoneering — The sport of traveling through technical canyons using some mix of hiking, scrambling, climbing, downclimbing, rappelling, stemming, swimming, pothole escapes, and problem-solving. Depending on the canyon, it can feel like hiking with ropes, a puzzle, a logistics exercise, a swimming workout, or a very scenic series of questionable decisions.
Capture — In practical canyon terms, this usually means securing the last person (or backpack) once it reaches a position where it can be managed from below.
C Class / Class C — A canyon with flowing water that complicates the technical descent. This is not beginner territory. Flowing current, waterfalls, hydraulics, and water-force management all raise the seriousness quickly.
Chimney / Chimneying — A movement technique using opposing pressure, often with the back on one wall and feet, knees, or rear end on the other.
Chockstone — A rock wedged in a narrow section of canyon. It may create an obstacle, a drop, an anchor opportunity, or all three.
Choss / Chossy — Loose, bad rock. If someone says, “That wall is chossy,” believe them the first time.
Colorado Plateau — The broad high-desert region spanning much of Utah, Arizona, Colorado, and New Mexico, and the homeland of a huge amount of American slot-canyon canyoneering. Utah alone has hundreds upon hundreds of documented slot canyons, which is either inspiring or a recipe for obsession. Usually both.
Contingency / Contingency Plan — Your backup plan. This might include extra gear, alternative exits, rope ascension ability, injury response, or simply a better idea than the one currently unraveling.
Contingency Block — A rappel rigging method that lets the person at the top lower more rope or convert the system if the rappeller gets stuck for whatever reason.
Conversion — Changing a rigged system from one mode to another. For example, converting a blocked rappel into a lower, or changing a loaded system so a stuck rappeller can be assisted.
Courtesy Rig / Courtesy Start — A temporary configuration that keeps the rappel attachment accessible for an easier start, then allows the final rigging to sit farther over the edge for retrieval. It needs a deliberate transition and last-person plan; it is not simply any handline or assist.
CRITR — A canyon-specific descender known for adjustable friction, especially useful on longer or more variable rappels.
Cryptobiotic Soil — Living desert soil crust made of organisms like cyanobacteria, lichens, mosses, algae, and fungi. It helps stabilize soil and support the ecosystem. In plain words: don’t stomp on it, because it can take decades to recover.
Crux — The hardest or most consequential section of a route or canyon. The crux may be technical, awkward, exposed, psychological, or all of the above.
D
DCL / DCR — Abbreviations for Down Canyon Left and Down Canyon Right. Same idea as LDC and RDC, just written a little differently depending on the beta source.
Deadman Anchor — An object buried in sand or soil and used as the anchor point. Useful, but not beginner stuff.
Descender / Descender Device / Rappel Device — The hardware used to create friction and control descent on rappel. Figure 8s, ATS, CRITR, SQWUREL, ATC variants, racks, and other specialized devices all fall into this category.
Deviation — Redirecting the rope path so the rappeller avoids a hazard, bad water line, sharp edge, or unwanted pendulum swing.
Disconnect — Remove a rope or tether connection at the planned point in a sequence. In aquatic canyons, disconnection timing is part of a trained water-specific plan; waiting until trapped in current may leave a connection impossible to release.
Double Strand — Rappelling on two strands of rope. Classic, common, and straightforward — as long as both strands reach the ground and you are actually on the correct strands.
Downclimb / Down-climb / Downclimbing — Descending an obstacle without rappelling. This is one of the biggest separators between newer and more experienced canyon travel. I’ve seen many obstacles where people rappel, and another person casually downclimbs.
Downstream / Down Canyon Orientation — Beta often assumes you know all directional language is based on facing down canyon unless specifically stated otherwise. This is why LDC and RDC matter.
Drainage — The water system that feeds and flows through a canyon. Understanding the drainage is a big part of flash-flood assessment.
Double-rope / double-strand rappel — Rappelling on two load-bearing rope strands. The ACA also refers to this as “double rope / Toss ’n Go” for this type of rigging. Do not confuse it with a blocked single-strand rappel that uses a separate pull cord only for retrieval.
Drop — A downward step or vertical obstacle. A drop may be rappelled, downclimbed, lowered, or bypassed. A count of drops is not necessarily a count of rappels; describe the obstacles and the group’s methods separately.
Drop-In — The point where the approach transitions into the canyon proper.
Dynamic Rope — A rope designed to stretch under load and absorb energy in a fall. Great for rock climbing. Much less common for standard canyoneering rappels, where static rope is preferred.
E
Edge Transition — The moment when a rappeller moves from standing terrain into weighted rope (i.e. horizontal to vertical). Often the most awkward part of a rappel, especially if the lip is rounded, sandy, sharp, sloping, or mentally offensive.
EDK (European Death Knot) — Slang for an offset overhand bend used to join ropes for retrieval. A stacked offset overhand adds a second overhand. Correct dressing, tightening, rope compatibility, and adequate tails matter. Do not confuse either with an offset figure-8 bend.
Egress — The path to exit the canyon.
Escape Side — In pothole or obstacle talk, this is the side you need to reach in order to continue.
Etrier — A short webbing or ladder-like aid used for stepping up during awkward starts, pothole escapes, or anchor access. Looks like a ladder.
Exposed — A section where a fall would have serious consequences.
Expansion Bolt — A bolt that secures itself in a drilled hole by mechanical expansion. Common, but condition still matters.
F
Fiddle Stick / Fiddlestick — A retrievable anchor tool that uses a small removable stick or toggle to hold a rigged system until the last person descends, after which the stick is pulled and the system is retrieved. Clever, useful, and not beginner territory. However, be curious about it and start asking experts how to use one and why.
Figure 8 — A rappel device and also a family of rope knots.
Fireman’s Belay — A bottom belay where the person below pulls down on the rope to stop or slow an out-of-control rappeller. Every capable canyoneer should know this.
First Descent — The first known (or publicized) descent of a canyon or route. This title has long carried prestige because there is still a real sense of exploration in the sport.
Force Multiplier — Any setup that increases force on an anchor, person, or system. Rope angles, bouncing, awkward redirects, and sloppy rigging can all make loads worse than people expect.
Free Hang / Free Rappel — Rappelling while fully suspended without wall contact. Scenic, airy, awkward, and for some people, deeply memorable in the “I would really like rock under my feet again” sort of way.
French System / French Rating — A canyon rating system commonly used in Europe. European canyon references often use this rather than the ACA-style North American system.
G
Ghost / Ghosting — Completing a canyon or rappel without leaving fixed anchor material behind. In other words: leave no trace, pack your stuff out.
Glue-In Bolt — A fixed anchor bonded into the rock with adhesive rather than mechanical expansion. Often strong when properly installed, but not immune to age, poor placement, or bad installation.
Guide Line — The tensioned line used in a guided-rappel setup. You are not rappelling on this line; it is steering or supporting your path away from a hazard.
Guided Rappel — A technique used to move a rappeller across or away from a hazard such as a hydraulic, dangerous pool, keeper pothole, or waterfall. It uses a tensioned guide line plus a rappel line so the person can descend while being directed to a safer landing.
Gully — A wider shallow ravine or drainage, often part of an approach or exit.
H
Hand Drill / Hand Drilling — Placing a bolt without a power drill, usually in remote canyons or where ethics, regulations, or practicality make power tools inappropriate. Slow, loud, tiring, and a reminder that permanent anchors should never be treated casually.
Handline — A rope used to hold for balance or assistance on a climb or downclimb. Important distinction: a handline is not the same thing as being on rappel.
Hang / Hanging Rebelay — A rebelay that occurs off the ground or while suspended, rather than at a comfortable ledge. This is where rope systems and calm thinking matter a lot. Not for beginners.
Harness — The gear you wear to connect yourself to rope systems. Waist belt, leg loops, belay loop, gear loops.
Hitch — A knot used to attach rope to another object or rope in a functional way. Clove hitch, munter hitch, autoblock, prusik — all in the family.
Hydraulic — Recirculating current or water feature that can trap a person, gear, or rope. Water is powerful, weird, and all consuming. Much respect needs to be paid to these. People have died in water hydraulics (due to drowning).
I
Ingress — Entering the canyon or beginning the route. The opposite of egress.
K
Keeper Exit — The actual move or final escape from a keeper pothole. This may involve pack tosses, potshots, partner assists, Etriers, hooks, leverage, and awkward teamwork.
Keeper Pothole — A pothole too deep or shaped too awkwardly to escape without specialized techniques such as partner assists, potshots, pack tosses, or other methods. One of the classic canyon-specific problems.
Keeper Sequence — The series of moves, tools, boosts, tosses, and escape ideas your group uses to solve a keeper pothole. Sometimes elegant. Sometimes very unique. Often memorable.
kN (Kilonewton) — The force rating used for climbing and canyoneering gear. One kilonewton is roughly 225 pounds of force. Your carabiners, ropes, and webbing are rated in kN, which is why this little abbreviation matters more than it first appears.
L
LAMAR / LAPAR — Terms related to Last Man (or Person) At Risk concepts. These refer to the reality that the final person in a group often faces the most complicated anchor and retrieval problems after everyone else has already descended.
Last Man Problem — The final person down must descend after everyone else, often with the least backup and the most complicated anchor situation.
LDC / Left Down Canyon — The canyon wall or feature on your left as you face downstream. Learn this early. It saves confusion and dumb mistakes.
Loop — A section of rope formed into a circular shape and where the rope crosses itself.
Lower — Instead of rappelling independently, the person above controls the rope and lowers the person below. Useful for beginners, injuries, difficult starts, pothole entries, and awkward sequences.
Upcanyon left / upcanyon right — Some beta may use upstream-relative language. Confirm the author’s orientation before acting on it. LDC/RDC are generally clearer because they are explicitly defined while facing downcanyon. It may be used in beta when the route is going UP a canyon/drainage to reach the actual technical slot canyon.
M
Marginal — Canyon slang for “less than inspiring” when referring to an anchor, move, or situation. If someone says, “That anchor is marginal,” that is not praise.
Marginal Anchor — An anchor that is less than ideal in quality, placement, material, or confidence.
Meat Anchor / Human Anchor — Using a person as a temporary human anchor in a planned sequence. ACA training treats human anchors as a legitimate technique, not merely a last resort. Load awareness, communication, sequencing, and a clear plan for the last person are essential.
Mechanical Advantage — Any hauling or tensioning setup that makes pulling easier by multiplying your input.
Monsoon Season — In the American desert of the Southwest, the summer period associated with increased thunderstorm activity and heightened flash-flood danger. Many canyoneers have died due to monsoon season and the rain/floods that catch them off-guard.
Multi-Stage Rappel — A descent with more than one drop or ledge. It may use one continuous rope or separate rappel stations. A rebelay is a separate rope attachment that requires a trained transfer; confirm the actual sequence in the beta.
Munter Hitch — A hitch used for belaying or lowering directly off a carabiner. In canyoneering, used as a last-resort if a descender device is lost.
N
Natural Anchor — An anchor built from naturally occurring features such as trees, rocks, chockstones, pinch points, or placed webbing around those objects. A huge part of canyon style and ethics.
Neoprene — Synthetic rubber used in wetsuits, gloves, booties, and other water-protection gear.
Nylon — A common synthetic material used in rope, webbing, and gear.
O
Overhang — A section of wall that leans outward past vertical. Overhangs matter on rappel because they change your body position, rope path, and interaction with the wall.
P
Pack Toss — Throwing a full backpack, usually with a rope attached, onto the escape side of a keeper pothole to help someone get out.
Partner Assist — Any movement technique where one or more teammates help another person get through an obstacle. Shoulder stands, stepping into hands, awkward human ladders, boosts, and counterweights.
PAS (Personal Anchor System) — A tether for attachment to a suitable anchor. Use the manufacturer-approved harness attachment and avoid slack or falls onto the tether. Before removing it to rappel, verify and function-check the complete rappel system while independently protected.
Pothole — A bowl-shaped depression eroded into rock, often filled with water. Some are easy. Some are keepers. Some are where optimism goes to die.
Pothole Escape — Any method used to get out of a pothole: partner assists, pack tosses, potshots, hooks, Etriers, leverage, capture moves, or simple brute awkwardness like a “beached whale” approach.
PotShot — A durable throwable bag filled on-site—typically with sand—and tossed beyond the escape lip of a keeper pothole to establish a weighted line for assistance or progression. It is an advanced canyon tool that requires practice and a complete last-person plan.
Progress Capture — Holding gained progress in a haul or tensioning system so you do not lose what you just earned.
Prusik — A sliding friction knot used to ascend a rope or as a secondary brake while descending. It is both a knot and, by extension, the loop used for it.
Pull Cord — A lightweight rope used to retrieve a fixed rappel line after descent. Light, handy, and absolutely not the rope you want to accidentally rappel on instead of the main line. People have died because of doing this.
Q
Quality Rating — Some canyon guides use a star-based quality rating alongside the technical rating to indicate how worthwhile or scenic a canyon is. Useful reminder: not every canyon is amazing just because it is hard.
Quick Link / Rapide — A threaded metal connector commonly used at rappel anchors. Confirm suitable strength, closure, condition, and compatibility with the rope or block; shape and opening size matter. Appearance alone does not establish a rating.
R
Ram / Steve Ramras — “Ram” is Steve Ramras’s long-used nickname/online handle. He is a longtime figure in the Utah canyoneering community and will show up often in older community discussions and trip reports.
Rap / Rapping — Slang shorthand for rappel / rappelling.
Rapide — Another name for a quick link.
Rappel — Descending a rope in a controlled manner using a device and harness. One of the central skills in the sport, though certainly not the only one.
RDC / Right Down Canyon — The canyon wall or feature on your right as you face downstream.
Rebelay / Re-Belay — A second anchor point partway down a wall or waterfall. This breaks a long rappel into stages or shifts the rope path away from hazards.
Redirect — Changing the path of a rope to improve the rappel line, reduce edge damage, avoid a watercourse, or otherwise make the system behave better.
Releasable System — Any rigging setup that can be lowered, adjusted, or converted while under load.
Retrievable Anchor — An anchor system designed so the last person can descend and then remove the system, leaving little or nothing behind.
Rich Carlson / “Rich” — A foundational figure in American canyoneering instruction and training history. ACA history credits Rich Carlson, Dave Black, and Charlie Oliver as the three people who formulated the early plan that became the American Canyoneering Association (ACA).
Rig Low / Rig High — Terms describing where the rope or anchor extension is set relative to the edge or intended line of rappel.
Rig Releasable — A rappel setup that can be lowered or released under load if needed.
Rigging — The process of setting up anchors, ropes, devices, and systems for descent or movement through a canyon.
Rope Groove — Wear cut into sandstone or soft rock by repeated rope movement under tension. Understanding rope grooves tends to change how people rig.
Rope Pad / Edge Protection — Equipment used to reduce specified rope-contact hazards. A fabric protector may resist abrasion without protecting against a sharp edge. Avoid or redirect dangerous edges and monitor the rope; no protector guarantees safety.
Route-finding — Figuring out where to go. Sounds simple. Often is not.
S
Safety Check — A final inspection of gear and setup before committing to a rappel or technical move. Harness? Device threaded correctly? Carabiner locked? On the right strand? Anchor sensible? Great. Now check again.
Safety Tether — A connection used to secure a person to a suitable anchor during positioning or transitions. A PAS is one type. Follow the tether and harness instructions, keep the connection controlled, and avoid a fall onto a slack tether.
Sandtrap — A retrievable anchor that uses sand as the holding medium when no natural or fixed anchor exists. Clever, desert-specific, advanced, and not something you want to learn for the first time when your whole group is already waiting at the drop.
SAR — Search and Rescue. Depending on the area, response may involve volunteers, park rangers, sheriff’s teams, fire/EMS personnel, and aviation crews. Help may be delayed or unable to reach the canyon.
Scramble / Scrambling — Movement somewhere between hiking and rock climbing. Hands may be used. Exposure may increase.
Scree — A slope of loose rock. Often found on ingress and egress sections within canyons.
“Send it” / “Send it, Bro!” — A phrase I still do not enjoy hearing in canyoneering. Borrowed from other action sports and usually said with varying levels of irony. Especially sad when said with gusto and the rappeller then rappels slowly.
Sequencing — The collection of movement choices used to get through canyon terrain: walking, stemming, bridging, handlining, downclimbing, rappelling, partner assists, and so on.
Sequencing Problem — A section of canyon where the main challenge is deciding how to move through it efficiently and safely, not necessarily how to rappel it.
Sheath — The protective outer woven layer of a rope.
Single-Line Rappel — Descending on one rope strand, often with a block or retrievable setup.
Sling — Webbing sewn or tied into a loop. Used for various uses: safety tether, PAS, ascending, lowering packs, and more.
Slog / Slogging — The tedious monotonous section where all you do is hike. Sometimes the canyon is amazing and the slog is awful. Sometimes the slog is half the story.
Slot Canyon — A narrow canyon with vertical walls and highly confined movement. This is what most people imagine when they hear “Utah canyoneering.”
Soft Capture — A less abrupt way of catching or assisting someone through a pothole exit, landing, or transfer.
Soloing / Solo Canyoneering — Descending a canyon alone without a partner.
SQWUREL — A canyon-specific rappel device allowing adjustable friction and commonly discussed alongside ATS and CRITR-style tools.
SRT (Single Rope Technique) — A broad term for movement and rope skills performed on a single fixed rope/strand, including descending, ascending, and transitions. In canyoneering, the exact rigging and retrieval plan still need to be specified; “SRT” by itself does not describe the whole system.
Static Rope — A low-stretch rope commonly used to rappel and ascend in canyoneering.
Stemming — Moving through a canyon by pressing hands and feet against opposing walls and advancing forward. One of the signature movement skills of the sport.
Stone Hitch — A hitch that can isolate two rope strands so they can be used independently in an appropriate system. The carabiner version and a retrievable toggle system have different checks and last-person procedures. Two-person loading requires an anchor and complete system suitable for the combined load; see the knot guide.
Swiftwater — Flowing water with enough force to significantly affect movement, rope work, rescue, or judgment. Normal dry-canyon habits do not always transfer safely here.
T
Technora — A high-performance, heat-resistant synthetic fiber used in some specialty ropes and cordage.
Toggle — A rigid or semi-rigid piece used in retrievable anchor systems such as fiddlestick-style setups or other toggle-based rigging.
Tom Jones — Founder of Canyoneering USA and Imlay Canyon Gear. A very big canyoneering name in the Utah and gear side of the sport.
Toss & Go — ACA terminology for a double-rope / double-strand rappel setup in which both rope strands are load-bearing. Like any rappel system, it has limitations and hazards that must be understood; it is not simply shorthand for “throw the rope and go.”
Trade Canyon — A popular, frequently descended canyon with published beta. Popularity does not guarantee maintained anchors, accurate reports, easy rescue, or conditions that match a previous descent.
Traverse — Moving horizontally across a wall, ledge, or feature.
Twin Strand Confusion — My unofficial term for when people look at two strands and stop being fully certain which one they are actually supposed to be on. This is why system checks exist.
U
Upclimb / Up-Climb — Climbing upward over an obstacle. Less common than downclimbing, but sometimes required because rockfalls, logjams, route changes, and canyon nonsense happen.
V
VT Prusik — A friction hitch variation sometimes discussed in rope systems. More common in climbing, arborist, or rescue circles than beginner canyon use, but useful to know exists. Seek out experts if you would like to learn more.
W
Water Class A / B / C — Water ratings in the North American canyon rating system.
• A = normally dry or shallow water
• B = standing water with no current or very light current, often with wading or swims
• C = water with current and/or waterfalls; ACA may refine Class C as C1 through C4 as current and water hazards increase
Watercourse — The actual line the water is taking down the canyon. In wet conditions, one of your big decisions is whether the rappel line should follow it, avoid it, or be guided away from it.
Webbing — Flat nylon or polyester material used for anchors, slings, and rigging. One of the most essential and most replaced items in canyon gear.
Wet Start — Beginning a rappel, entry, or sequence directly in water or while already swimming.
Y
YDS (Yosemite Decimal System) — The North American climbing difficulty system. Sometimes used when a canyon involves actual rock-climbing style moves, especially upclimbs or bypasses.
Z
Zion — The correct name is Zion National Park. Singular. Clean. Elegant. Correct.
“Zions” — What people from Utah say when they mean Zion because Zions Bank exists and has apparently done lasting damage to Utah vocabulary. It’s no plural and it’s not possessive. Yes, people say it. Yes, I notice it. Yes, it makes my eye twitch a little. Among canyon friends, it is a running joke:
“Anyone going to Zions National Bank Park this weekend?”
“I’m heading down to Moabs.”
“Anyone going to Bryces Nationals Parks?”
“Thinking about canyoneering in the Swells.”
08.5 Things You May Hear in a Canyon
Some canyon language is technical. Some of it is shorthand. Some of it only makes sense after you have suffered together for eight hours.
These are not formal glossary entries, but they are absolutely part of canyon language. You will hear them in parking lots, on approaches, at anchors, while hanging on a wall, while chest-deep in cold water, or while someone confidently says something reassuring that absolutely deserves a follow-up question.
If you spend enough time around the sport, these phrases eventually stop sounding strange. Until then, consider this your translation guide.
08.6 A Small Warning
Tone matters. “Good times,” “casual,” and “we’re almost there” can mean exactly what they say—or almost the complete opposite.
08.7 Rappel Calls & Rope Commands
“On rappel.”
TRANSLATION The person has weighted the rope and is now actively descending.
“Off rappel.”
TRANSLATION The person is off the rope, and the line is clear for the next person.
“Rope free!”
TRANSLATION The rope is available for the next person to use.
“Watch out below!”
TRANSLATION Something is coming down — rope, rock, debris, sand, water, or occasionally a backpack.
“Tension!”
TRANSLATION Pull the rope tight.
“Slack!”
TRANSLATION Give more rope.
“Take!”
TRANSLATION Remove slack and hold the rope under tension.
“That’s me.”
TRANSLATION The rope being pulled has come tight to the speaker. Confirm the intended meaning; it does not verify that a rappel rope reaches the landing.
“Lower me.”
TRANSLATION The person wants to be lowered instead of continuing as a normal rappel.
“Fireman me.”
TRANSLATION Give me a fireman’s belay from below while I rappel.
“Check my rigging?”
TRANSLATION Please inspect my setup before I commit to it.
“Block side.”
TRANSLATION Ambiguous shorthand. Point out and trace the rappel strand and retrieval strand at the anchor instead of relying on this phrase.
“Rappel side.”
TRANSLATION The rope strand you descend on.
“Pull side.”
TRANSLATION The rope strand you pull to retrieve the rope after the rappel.
“The pull side is this side.”
TRANSLATION This is the strand that retrieves the system — not the one you should be rappelling on.
“Let’s rig this releasable.”
TRANSLATION Set the rappel up in a way that allows it to be lowered, adjusted, or converted if needed.
“Let’s rig it blocked.”
