BOOT CANYON. Boot Canyon is a deep, rugged valley cut by an intermittent stream high in the Chisos Mountains of Big Bend National Park in southern Brewster County. The headwaters of its drainage are near the South Rim of the Chisos Mountains, south of Emory Peak (at 29°14' N, 103°17' W). The stream is fed by Boot Spring. The canyon runs northeast for four miles to its mouth near the upper end of Juniper Canyon (at 29°15' N, 103°16' W). Boot Canyon descends rapidly some 2,500 feet. Near its midpoint stands a giant rock spire called the Boot, for which the canyon was named. Just below the Boot the canyon deepens over 1,000 feet in less than half a mile, between massive cliffs. With the exception of a few scattered grassy meadows, the greater part of Boot Canyon is wooded. The vegetation throughout the drainage includes a mixture of oak-juniper-piñon woodland and conifer forest, with the former predominant in most areas. Boot Canyon also shelters the only native stand of Arizona cypress in Texas.
