Named for Jep and Thomas Ryan, who had a homestead that contained a rare a water source at the base of this mountain. They were also coowners with Johnny Lang of the famous “Lost Horse Mine” which was 3.1 miles south of this summit. In his Joshua Tree National Monument, A Visitor’s Guide Bob Cates notes that this mine was locally the most successful operation of its kind producing about 9,000 troy ounces of gold (ca. 1890’s). The remains of the village and the old 10-stamp mill are still visible.
