The White Rim Sandstone Member of the Permian Cutler Formation in Canyonlands National Park, southeastern Utah, was deposited in a coastal eolian environment. The White Rim consists of three types of eolian deposits: dune, interdune, and sabkha. Characteristics of the dune deposits are large-to medium-scale, unidirectional, tabular planar crossbed sets; high-index ripples oriented parallel to the dip direction of the foresets; inverse graded laminations formed by ripple migration; sand-flow toes; and raindrop impressions. Interdune deposits are of two types, erosional and depositional, formed under varying degrees of wetness. Erosional interdune deposits are characterized by thin, coarse sand to granule size, bimodal...
