Description :
This paper describes compositional features of late Quaternary surficial deposits (including modern and buried soils) in a semi-arid grassland. The study area is in the Needles district of Canyonlands National Park of the Colorado Plateau. The central aims are to characterize textural, mineralogical, and chemical properties that might indicate dust and nutrient contents of deeper substrates; determine the causes for variations in these properties that are presumed to elucidate changing conditions of landscape stability in the study area as well as, perhaps, environmental change in dust-source areas; and assess the potential ecologic importance of these variations.
