Geology
Round Mountain is made of gray hornblende plagioclase trachyte. It is sometimes called an extinct bysmalith, or igneous volcanic plug, but is more widely considered a shallow intrusion (laccolith) related to the La Sal Mountains immediately north.[4]
Climate
Spring and fall are the most favorable seasons to visit Round Mountain. According to the Köppen climate classification system, it is located in a cold semi-arid climate zone with cold winters and hot summers.[5] Summers highs rarely exceed 100 °F (38 °C). Summer nights are comfortably cool, and temperatures drop quickly after sunset. Winters are cold, but daytime highs are usually above freezing. Winter temperatures below 0 °F (−18 °C) are uncommon, though possible. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
