Abstract

Terracettes in the western Iowa Loess Hills were characterized morphogenetically, with field observations suggesting high association with ungulate activities. A new class of mega-terracette is recognized that characterizes study-area forms orders of magnitude larger than those discussed by others. This addition to the prior terracette morphologies adds to understanding of concepts of equifinality in which terracettes result from multiple processes. These mega-terracettes are related to ungulate activities of geophagy, soil transport from hooves, compaction, smearing, pawing, and wallowing (dust bathing) as well as to the effects of variable soil moisture on erosion of the forms
