TRES HERMANAS MOUNTAINS
TRES HERMANAS MOUNTAINS. The Tres Hermanas Mountains, also known as the Shely Peaks, are seven miles southwest of Tesnus and twenty miles southeast of Marathon in northeastern Brewster County (centered at 30°01' N, 102°56' W). The middle peak of the three has an elevation of 5,210 feet above sea level, rising some 1,610 feet above Rough Creek, one mile west. Its neighbors to the west and northeast have elevations of 5,155 and 5,042 feet above sea level, respectively. Shallow, stony clay loams in the area support juniper, oak, grasses, chaparral, and cacti. The peaks are called the Tres Hermanas, Spanish for "three sisters," not only because of their similarity and proximity, but also after Anita, Ida, and Aurora Brooks, the daughters of mining engineer H. W. Brooks.
