Red Rock National Park
Red rock features prominently in place names of Southwest USA - New Mexico, Arizona and California each have a Red Rock State Park and there are several similarly named towns in these and other states. Nevada has at least three Red Rock Canyons; two are in sections of the Toiyabe National Forest near the center of the state but by far the most well-known is location is along the east side of the Spring Mountains - one of the ranges of hills that surround Las Vegas in most directions.
Just five miles from the edge of the city, the flat land rises to a great colorful escarpment, formed along a fault zone (the Keystone Thrust) with peaks over 8,000 feet, and including huge cliffs and ravines composed of bands of grey, white and red sandstone, all heavily eroded. The wide empty plains beneath the hills are studded with Joshua trees and other plants typical of the Mojave Desert, contributing to a most impressive spectacle.

I personally recommend this tour to anybody who appreciates the marvellous scenary of the geologic formations, wildlife, deserts, the dam and historic areas.
