Particle‐size distribution, x‐ray diffraction, organic carbon, and calcium carbonate equivalent were measured on selected Calciorthids and Camborthids formed in stone‐free surficial deposits on a structural plain in east‐central Utah. Mylar balloons were tracked with theodolites to determine the circulation of prevailing winds over the mountain slopes and adjacent land forms. Particle‐size distributions (80% silt and very fine sand) and observed wind circulation patterns (strong westerly mesoscale with hydraulic jump) indicate that wind has had a strong influence on the soils and that wind is directly responsible for the complex soil distribution on the land form. Presence of cylindrical soil structure units at depths greater than normal for cicada activity suggests that these features are relict and that these cylindrical soil structure units have been buried. Variable depths over short horizontal distances to K horizons further suggest burial by wind.
