SIERRA AGUJA. The Sierra Aguja range straddles the Big Bend National Park boundary seven miles south of Terlingua in southwestern Brewster County and extends for two miles from the northwest to the southeast (centered at 29°14' N, 103°38' W). The range is 1½ miles across at its widest point. The highest peak in the Sierra Aguja has an elevation of 2,843 feet above sea level, rising 600 feet above Terlingua Creek, a mile east. The surrounding shallow, stony soils support live oak, piñon, juniper, and grasses. Aguja means "needle" in Spanish.
