Description

Rainbow Mountain is located 17 miles (27 km) 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 miles (1.00 km) immediately north of Mount Wilson. [3] 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 2,500 feet (762 meters) 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. [1]

Climate

Rainbow Mountain is set within the Mojave Desert which has hot summers and cold winters. [4] 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. [5] 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."

<span class="mw-page-title-main">Checkerboard Mesa</span>

Checkerboard Mesa is an iconic 6,520+ ft elevation Navajo Sandstone summit located in Zion National Park, in Kane County of southwest Utah, United States. Checkerboard Mesa is situated immediately southwest of the park's east entrance, towering 900 feet above the Zion – Mount Carmel Highway. Its nearest neighbor is Crazy Quilt Mesa, one-half mile immediately west, and separated by Checkerboard Mesa Canyon. This canyon holds pools of rainwater which provide a vital source of water for resident bighorn sheep. This peak was originally named Checkerboard Mountain by the park's third superintendent, Preston P. Patraw. The landform's toponym was officially adopted in 1935 by the U.S. Board on Geographic Names. The descriptive name stems from the cliff's distinctive multitudinous check lines in cross-bedded white sandstone which give the impression of a checkerboard. The horizontal lines are caused by cross-bedding, a remnant of ancient sand dunes. The vertical and sub-vertical lines formed by the contraction and expansion of the sandstone caused by temperature changes, freezing and thawing cycles, in combination with wetting and drying. Precipitation runoff from this mountain drains into tributaries of the Virgin River.

It is set on the west side of the North Fork Virgin River which drains precipitation runoff from this mountain. It is wedged between Behunin Canyon and Heaps Canyon, with the popular Emerald Pools set at the southeast foot of this mountain. Its neighbors include Mount Majestic, Cathedral Mountain, The Great White Throne, Red Arch Mountain, Mountain of the Sun, and Lady Mountain. This feature's name was officially adopted in 1934 by the U.S. Board on Geographic Names.

It is so named because it resembles an embracing couple. This geographical feature's name was officially adopted in 1982 by the United States Board on Geographic Names. Older USGS maps have the feature's name misplaced by about one-half mile to the southeast. The first ascent of the summit was made May 4, 1960, by Layton Kor, Harvey Carter, and John Auld via the five pitch, class 5.11a route named Long Dong Wall. The first free ascent was made in 1977 by Andy Petefish, Tom Stubbs, and Jim Pearson. Some climbers alternatively refer to Kissing Couple as "Bell Tower."
