|Other slot canyon locations in the Southwest.
The hardest-to-reach group of Utah slot canyons are found along the Dirty Devil River, north of Lake Powell, mostly on the east side where access is more difficult. Main locations are Happy Canyon, Larry Canyon, Sams Mesa Canyon and various forks of Robbers Roost Canyon. North of here is another group including Blue John Canyon, also with several branches, and Moonshine Wash, while to the west, Moab has some narrow canyons though the rocks hereabouts are not generally conducive to slot formation. Professor Creek is one nice drainage in this region.
- Anza Borrego Desert State Park, California - desert badlands with a variety of short slot canyons
- Blue John Canyon, Utah - deep, branched slots near the Green River, some requiring rappelling
- Buckwater Draw, Colorado - dryfalls and short slots close to Dinosaur National Monument
- Holeman Slot, Utah - short narrows in Canyonlands National Park, near the Green River
- Lovell Wash - curvy slot though thin-bedded sandstone, near Lake Mead
- Moonshine Wash, Utah - pretty narrows in the San Rafael Desert
- Professor Creek, Utah - pleasant canyon with a year-round stream
True slot canyons are restricted to the Colorado Plateau and even here only in certain types of rock (mostly the Navajo, Wingate and Cedar Mesa strata) but narrow ravines are still found elsewhere throughout the Southwest. In central Arizona, below the Mogollon Rim that marks the southern edge of the plateau, the many streams and creeks that flow down from the high country often erode sheer sided canyons, not continuosly narrow but with enclosed sections, often flooded, containing chokestones, waterfalls and the added attraction of large cacti, including saguaro in many of the lower elevation drainages. The amount of water and hence ease of exploration varies a lot throughout the year, though often access is always difficult owing to the remoteness and roughness of the surrounding terrain, so some are never very easy to follow. There are several well known canyons in and around Sedona, including West Clear Creek and Wet Beaver Creek, but most of the best are further south - Tonto Creek and tributaries, Aravaipa Canyon, Salome Creek, Cibecue Creek, the Salt River and countless others.
The California and Colorado mountains have similar gorges, with waterfalls and V-shaped channels but no true slot canyons. The California deserts do have some though. One type are found in low elevation canyons which experience flash floods, where narrow channels can be formed - the most well known are in Death Valley which has a variety of narrow twisting ravines with unusual strata but many less well known valleys have other examples. Another type is found in conglomerate rocks such as in Anza Borrego Desert State Park, which have erosional properties similar to sandstone and also form quite narrow slots, though they tend to be quite short.
Further afield, another interesting location is in and around Big Bend National Park in Texas, where the Rio Grande River flows through a series of deep gorges, with narrow side canyons.
