Dominating this immense, pristine desert landscape near the California border is Black Mesa, 10 miles long and 1,000 feet above the surrounding desert, with edges dissected into a maze of winding canyons. Remnants of ancient mesas and isolated hills jut like islands in the sea of vast encircling desert plain. After wet winters, spring brings a profusion of blooms on ocotillos, cacti, and flowering shrubs and annuals. A historic old trail from Baker Spring and numerous feral burro tracks provide access to the Wilderness. Warm Springs and other water sources allow for an extended (if carefully planned) backpacking or horsepacking trip. Map and compass skills are required.
