East Rim Ranch lies at 4,000’ elevation and is located 28 miles south of Alpine on US Hwy 118 between Alpine and Big Bend National Park in Brewster County, Texas. The ranch is just south of Elephant Mountain , a 27,000-acre wildlife management area owned by the state of Texas and managed by Texas Parks and Wildlife. The ranch consists of approximately 5,060 acres including 3 miles of frontage on HWY 118, with major north south creek, rolling terrain with 200-foot-high limestone hills. It is part of the desert grasslands and home to elk, mule deer, blue quail, wild turkey, desert big horn sheep, and scimitar horned oryx. In addition to the 27,000-acre Elephant Mountain preserve, the ranch is surrounded by three large ranches; the O2 Ranch which is 270,000 acres is to the south and west, the 45,000-acre Black Mesa Ranch located to the east of ERR and the Y-Bar Ranch to the north is 30,000 acres. These three ranches afford protection, long-term ownership and strong ranch management that will continue to promote good land stewardship in the Calamity Valley.
