Genesis and Morphology of Soils Associated with Formation of Laramie Basin (Mima‐Like) Mounds in Wyoming
Abstract Small mounds of varied origin are a common microrelief feature over much of the western United States. In Wyoming's Laramie Basin, soil genesis and mound formation were studied in a 27.5 m long trench dug to expose intermound soils with strongly developed horizonation (Borollic Haplarg...
