BOOT ROCK. Boot Rock is a mile east of Emory Peak in the Chisos Mountains of Big Bend National Park in southern Brewster County (at 29°15' N, 103°17' W). It is a slender stone tower that stands isolated between massive cliffs in a high, heavily wooded canyon. It resembles an inverted cowboy boot and is referred to in some sources as the Cowboy Boot; local residents call it the Boot. Boot Rock is an erosional remnant, a surviving portion of what was once probably a dike cutting through the Chisos Formation.
