Bob Thompson Peak is a 7340feet summit in Cochise County, Arizona, United States.

Description

Bob Thompson Peak is located 12miles south of the city of Sierra Vista on the boundary that Coronado National Memorial shares with Coronado National Forest.[3] It is the second-highest point within the memorial which is administered by the National Park Service.[4] The peak's slopes are covered by silk tassel, sumac, pointleaf manzanita, agave, yucca, and sotol.[5] Precipitation runoff from this peak's slopes drains east to the San Pedro River drainage basin.[3] Topographic relief is significant as the summit rises 2040abbr=offNaNabbr=off above Ash Canyon in one mile (1.6 km). The nearest higher neighbor is Montezuma Peak, to the west-southwest.[3] The mountain's toponym was officially adopted in 1959 by the U.S. Board on Geographic Names.[1] [6] Robert "Bob" Thompson was a long-time Forest Service ranger who collected data in 1924 for determining the commercial value of land in the Huachuca District of Coronado National Forest.[7] [8] [9]

Geology

Bob Thompson Peak is composed of siliceous volcanic rock,[10] breccia, tuff, granite, hornfels, and limestone.[11] The mountain is located on the hanging wall of the regional, northwest-trending Cochise thrust fault. The movement of this fault transported Jurassic units of collapse-breccia from the Montezuma Caldera over younger Huachuca granite.

Climate

According to the Köppen climate classification system, Bob Thompson Peak is located in a semi-arid climate zone with mild winters and hot summers. Summer starts off dry, but progressively gets wetter as the monsoon season approaches during the months of July and August. 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 are uncommon, though possible. This area receives less than 20abbr=offNaNabbr=off of annual rainfall, and snowfall is generally light during the winter.[12]
