Rainbow Mountain (Clark County, Nevada)

Rainbow Mountain is a 6811 ft mountain summit in Clark County, Nevada, United States.

Description
Rainbow Mountain is located 17 mi west of downtown Las Vegas in the Spring Mountains which are a subrange of the Great Basin Ranges. It is set on land administered by the Bureau of Land Management as the Red Rock Canyon National Conservation Area, part of the Rainbow Mountain Wilderness Area. The peak is 0.62 mi immediately north of Mount Wilson. Precipitation runoff from the mountain's slopes drains north into Red Rock Wash and south into Oak Creek. Topographic relief is significant as the summit rises 2500. ft above Oak Creek Canyon in less than one-half mile (0.8 km). This mountain's descriptive toponym has been officially adopted by the U.S. Board on Geographic Names.

Climate
Rainbow Mountain is set within the Mojave Desert which has hot summers and cold winters. The desert is an example of a cold desert climate as the desert's elevation makes temperatures cooler than lower elevation deserts. Due to the high elevation and aridity, temperatures drop sharply after sunset. Summer nights are comfortably cool. Winter highs are generally above freezing, and winter nights are bitterly cold, with temperatures often dropping well below freezing.

Geology
Rainbow Mountain is composed of Aztec Sandstone which formed about 180–190 million years ago as lithified sand dunes in a desert during the Early Jurassic. The red, orange, and brown coloring of the sandstone is caused by the presence of iron oxide or hematite. Red spots in the buff sandstone are iron oxide concretions called "Moqui marbles."
