Dark Canyon Wilderness, Dark Canyon ISA Complex, and Cheesebox Canyon WSA Trails Professional Review and Guide
"Both the designated wilderness the adjacent instant study area (ISA) have the same name, Dark Canyon. The tributaries of Dark Canyon are Black Steer, Youngs, Lost, and Lean-To Canyons—all of which can be explored as side trips of a Dark Canyon expedition. Fable Valley is part of the Dark Canyon ISA Complex administered by the BLM, but it’s a tributary of Gypsum Canyon, accessible from the Dark Canyon Plateau but not from the main canyon.
Cheesebox Canyon, part of the White Canyon area near Natural Bridges National Monument, is separated from the Dark Canyon area by dirt access roads and a ridge of highcountry. This trail guide includes descriptions of Sundance Trailhead to Dark Canyon, Woodenshoe, Dark, and Peavine Canyons, and Horse Pasture Canyon to Scorup Cabin."
