Slot Canyon Topography & Regions
Module 16
Most canyoneering in the United States is found on a topographic feature called the Colorado Plateau. This area is primarily located in southern Utah, west Colorado, north-west New Mexico, and the northern part of Arizona.
The Colorado Plateau encompasses the four-corner states and region of the Southwest part of the United States. From the NPS.gov website, it says, “Originally named by John Wesley Powell, the Colorado Plateau comprises a series of tablelands (plateaus or mesas) located within an immense basin surrounded by highlands. Stream valleys that are typically narrow and widely spaced dissect the region, as do larger valleys, including the most spectacular – the Grand Canyon. “


Colorado Plateau
Found in southern Utah, western Colorado, northwestern New Mexico, and northern Arizona
Contains one of the largest concentrations of slot canyons in the world
Features: Plateaus, mesas, narrow stream valleys, and iconic landmarks like the Grand Canyon
Utah: Canyoneering Mecca
Home to over 650 documented slot canyons, the highest concentration in the U.S.
Considered the “mecca” for slot canyoneering
Other Notable Regions
Arizona: Over 500 canyons, many slot canyons
California: Over 700 canyons, but few true slot canyons (primarily found in Death Valley)
Canyons vs. “Routes”
Canyons: Steep, narrow channels carved by water
Routes: Larger drainage areas with rappels, downclimbs, and tricky navigation
Both offer unique adventure opportunities, though routes may not involve true slot canyon experiences
Why Utah and Arizona?
Visitors flock to these areas for the chance to experience narrow, stunning slot canyon experiences
While “true” slots are uncommon in California, unique slot canyons in Death Valley NP exist
