The White Rim Sandstone Member in Canyonlands National Park was deposited in an eolian system. Unlike many other depositional environments, no single facies model exists for eolian systems, resulting in no preferred vertical sequences nor any consistent lateral changes (Walker, 1979). Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone. When there is a significant amount of clay or silt, geologists refer to the rock as argillaceous sandstone. The color of sandstone varies, depending on its composition.
