WHIRLWIND MESA. Whirlwind Mesa straddles the Brewster-Presidio county line twenty-five miles southwest of Alpine (at 30°00' N, 103°47' W). The highest elevation on the mesa is 5,537 feet above sea level, some 1,300 feet above Hackberry Drive, two miles to the south. The area's shallow, stony soils support Mexican buckeye, walnut, persimmon, desert willow, scrub brush, and grasses.
