Those and other sandstones, of all colors, are also notable for their fine-grained and smooth surfaces, hence the name slickrock. The striking reddish hue of many of the sandstone units, formed by oxidized iron, is clearly the source of the red rock name. The terms r ed rock and s lickrock are often used for this territory. It is a wonderland for those who appreciate rocks and rugged natural landscapes. I’ve been drawn to this region since reading works by Edward Abbey back in my early college years. Most of the rocks are sedimentary types in various shades of red, orange, yellow, tan, brown, purple, and green they include shale, sandstone, limestone, and conglomerates. The landscape is sculpted into dramatic cliffs and arches, domes and towers, fins and hoodoos, mesas and buttes, slot canyons, and deeply carved canyons. Extending across the Four Corners region where the borders of Utah, Colorado, New Mexico, and Arizona meet, high deserts with a scattering of forests cover the plateau. Grand Canyon, Zion, Arches, Canyonlands, and other national parks on the Colorado Plateau encompass some of the most spectacular scenery on Earth.
