Nature
Round Mountain is a 6,185-foot summit in southeastern Utah near the upper end of Castle Valley, about 10 miles east-northeast of Moab. Though modest by regional standards, it rises strikingly, climbing about 1,000 feet above the valley floor in just 0.4 miles. Its runoff feeds Castle Creek within the Colorado River watershed, and Castleton Tower is the nearest higher peak. Geologically, the mountain consists of gray hornblende plagioclase trachyte and is most widely regarded as a shallow intrusion, or laccolith, related to the La Sal Mountains rather than an extinct volcanic plug. It stands in a cold semi-arid climate with hot summers, cold winters, light snowfall, and low annual precipitation.
