Red Rock Canyon National Conservation Area view 031513.JPG

The Red Rock Canyon National Conservation Area in Clark County, Nevada, is an area managed by the Bureau of Land Management as part of its National Landscape Conservation System, and protected as a National Conservation Area. It is about 15 miles (24 km) west of Las Vegas, and is easily seen from the Las Vegas Strip. More than two million people visit the area each year.

The conservation area showcases a set of large red rock formations: a set of sandstone peaks and walls called the Keystone Thrust. The walls are up to 3,000 feet (910 m) high, making them a popular hiking and rock climbing destination. The highest point is La Madre Mountain, at 8,154 feet (2,485 m).

A one-way loop road, 13 miles (21 km) long, provides vehicle access to many of the features in the area. Several side roads and parking areas allow access to many of the area trails. A visitor center is at the start of the loop road. The loop road is also popular for bicycle touring; it begins with a moderate climb, then is mostly downhill or flat.

Red Rock Canyon is a side-canyon accessible only by an unmaintained primitive road from the scenic loop which mostly only off-road or high clearance vehicles can access. State Route 159 cuts through an unnamed but often-visited valley; it is commonly, but mistakenly, referred to as Red Rock Canyon. The Wilson Cliffs, or Keystone Thrust, a massive wall of rock, can be seen to the west from SR 159.


Toward the southern end of the National Conservation Area are Spring Mountain Ranch State Park; Bonnie Springs Ranch, which includes a replica of a western ghost town; and the village of Blue Diamond.

Red Rock Canyon National Conservation Area is considered the future event for Burning Man should Burning Man Organization and the Bureau of Land Management (BLM) under the Trump administration decide to not renew the 10 year permit for the Black Rock Desert in 2020.

The first humans were attracted to the Red Rock area due to its resources of water, plant, and animal life that could not be easily found in the surrounding desert. Hunters and gatherers such as the historical Southern Paiute and the much older Archaic, or Desert Culture Native Americans, have successively occupied this area.

As many as six different Native American cultures may have been present at Red Rock over the millennia. The following chronology is an approximation, from the present to ancient pre-history:

Numerous petroglyphs, as well as pottery fragments, remain today throughout the area. In addition, several roasting pits used by the early Native Americans at Red Rock provide further evidence of human activity in the past.

In the early 20th century, around the time the first European Americans settled in nearby Las Vegas, the Excelsior Company operated a small sandstone quarry near the northern area of the scenic loop. It proved to be uneconomical and was shut down. Evidence of the quarry's existence includes some of the huge sandstone blocks that have been left behind.

The Red Rocks have been a film location for such movies as Roy Rogers and his horse Trigger in Bells of San Angelo (1947) and was a location for The Stalking Moon with Gregory Peck in 1968.

In 1967, the Bureau of Land Management designated 10,000 acres (16 sq mi; 40 km2) as the Red Rock Recreation Lands. By 1990, special legislation changed the status of the Red Rock Recreation Lands to a National Conservation Area, a status that also provides funds to maintain and protect it.

The Howard Hughes Corporation, developer of Summerlin, has transferred land adjacent to the protected area, to provide a buffer between development and the conservation area. On the west side, Red Rock Canyon National Conservation Area is adjacent to the Spring Mountains National Recreation Area.

The conservation area is one of the easternmost parts of the Mojave Desert; the lowest elevation of the area, from 3,600 to 4,500 feet (1,100 to 1,400 m), is in the Lower Sonoran Zone, while the area from 4,500 feet (1,400 m) up is in the Upper Sonoran Zone. The character of the sandstone layers is such that a number of year-round springs may be found in the recesses of the side canyons.

Some 600 species of plants are known in the area. Common types in the valley floor include the Joshua tree, Mojave yucca, banana yucca, creosote, and blackbrush. Higher up the Utah juniper and Sonoran scrub oak (also called scrub live oak) come to dominate. Agave is easy to spot in red rock niches, with its thick low leaves and flowering stem that reaches twice the height of a man. The Calico Tanks trail has a plaque about prehistoric agave roasting pits. Ponderosa pines may be found at the top of the valley, where it connects to the Spring Mountains.

Wild burros are a familiar sight, as are rabbits and ground squirrels. Desert bighorn sheep are occasionally seen at higher elevations. During rare spring and summer rainstorms, tiny red-spotted toads can be seen emerging from pools of water.

The Conservation Area is protected habitat for the desert tortoise. A habitat at the Visitor Center houses eight females and two males.

The Red Rock area has a complex geological history, which over millions of years, helped create the region's dramatic landscape.

The Red Rock area was under an ocean basin during the Paleozoic Era 600 million years ago. Up to 9,000 feet (2,700 m) of limey sediments were deposited and eventually lithified to limestone.During the Mesozoic Era 250 million years ago, the earth's crust started to rise due to tectonic shifts, and marine shales and sandstones were deposited. As the basin became isolated evaporite formations of salt and gypsum were deposited. Oxidation of the iron minerals in the sediments resulted in the red colors of some of the rocks. Deposition by streams and in swamp environments resulted in the formation of petrified wood in the area.

By 180 million years ago, the climate continued to change and the area became a desert with vast expanses of huge shifting sand dunes. These dunes accumulated over a broad area, up to 0.5 miles (0.80 km) thick, and were lithified, cemented with calcium carbonate and iron oxides. They developed as the colorful Aztec Sandstone.
