Vermilion Cliffs
From Wikipedia, the free encyclopedia
The Vermilion Cliffs are the second "step" up in the five-step Grand Staircase of the Colorado Plateau. Reddish or vermilion-colored cliffs are found along U.S. Highway 89 and U.S. Highway 89A near Kanab, Utah (and near Navajo Bridge in Arizona). They extend from a location near Page, Arizona, west for a considerable distance, in both Arizona and Utah. 112,500 acres (455 kmĀ²) of the region were designated as the Paria Canyon-Vermilion Cliffs Wilderness in 1984, and an even greater area was proclaimed Vermilion Cliffs National Monument in 2000. Famous locations in the cliff area include Lee's Ferry, Glen Canyon (a national recreational area), The Wave, Coyote Buttes, and others.
The cliffs sat astride an important route from Utah to Arizona used by settlers during the 19th Century. The area was throughly explored by the Mormon pioneer and missionary Jacob Hamblin who started a ranch at the base of the cliffs in House Rock Valley. Modern U.S. Highway 89A basically follows the old wagon route past the cliffs through House Rock Valley and up the Kaibab Plateau to Jacob Lake.
The Vermilion Cliffs are made up of deposited silt and desert dunes, cemented by infiltrated carbonates and intensely colored by red iron oxide and other minerals, particularly bluish manganese. In the spring, after a good winter rain, the valley between Highway 89 and the Vermilion Cliffs will be covered with a carpet of desert mallow and other spring flowers.
In the image below, Highway 89 is atop the yellow rocks capping the first step of the series, the Chocolate Cliffs and will turn east (to the right) upon entry to the valley below, ultimately crossing the Colorado river at Marble Canyon via the Navajo Bridge.
