7-mile hike with 1,400-foot elevation gain from near the mouth of Titus Canyon, across the alluvial fan deposits along the base of the Grapevine Mountains, down a steep path to a large wash, and into the mouth of Fall Canyon, with its colorful striated walls of orange and black dolomite and limestone. As we progressed, the passage up the canyon got narrower and narrower. After 3.4 miles, we came to a dead end, where a dryfall blocked any further progress up the canyon. So instead of scrambling up rocks, we hiked back from whence we came.
