Hellsgate Wilderness Trails Professional Review and Guide
"Knifing down off the mogollon rim to the Salt River, Tonto Creek is the centerpiece of the Hellsgate Wilderness. Cutting deeply into granite, Tonto and its main tributary, Haigler Creek, have carved deep canyons that rise in places to more than 1,500 feet above the stream bottoms. The wilderness derives its name from the turbulent confluence of Tonto and Haigler Creeks, which pioneer settlers dubbed Hells Gate.
Plants associated with the Sonoran Desert—saguaro cactus, ocotillo, agave, and cholla—grow in the lower elevations of the wilderness. The riparian gallery features willow, sycamore, cottonwood, ash, and Arizona walnut. At mid-level elevations you find scrub oak, alligator juniper, piñon, and manzanita. Ponderosa pine and Douglas fir grow in the higher, cooler elevations."
