Black Mountain is the ninth-highest peak in the Davis Mountains and it ranks as 21st-highest in the state of Texas.[1][2]Topographic relief is significant as the summit rises over 2,000 feet (610 m) above Big Aguja Canyon in 1.25 mile (2 km). The mountain is composed of 35 million-year-old igneous rock.[4] Based on the Köppen climate classification, Black Mountain is located in a semi-arid climate zone with hot summers and cold winters.[5] This climate supports Douglas fir, aspen, Arizona cypress, maple, ponderosa pine, and madrone growing on the slopes.[6] Precipitation runoff from the mountain's slopes drains into the Pecos River watershed.[1] The mountain's toponym has been officially adopted by the United States Board on Geographic Names,[3] and has been reported in publications since at least 1902.[7]
