To remind yourself of the subtle dangers of the Canyonlands, we suggest watching the movie 127 Hours before taking on this hike. Make sure you know how to handle a map and have plenty of water before descending into a literal labyrinth, which is ensconced in a sandstone prison heated to a toasty 110° in the daytime. Local rangers suggest bringing along a GPS unit to help deal with the fact that this “trail” is rather trail-less. Dead-end canyons, dry washes, and continuous sandstone features tend to blend together, often stymying the most savvy of adventurers. Don’t forget to file your detailed itinerary with a ranger—most people don’t survive a self-amputation.
