A regional remote sensing study was conducted to assist in evaluating the mineral resource potential of five wilderness study areas in western Colorado and eastern Utah, centered on Moab, Utah. Numerous Landsat Multispectral Scanner (MSS) images were used as the basis for a lineament analysis, and two Landsat MSS images were processed for limonite mapping. No Landsat Thematic Mapper data were available for this study. The Behind the Rocks, Indian Creek, and Butler Wash Wilderness Study Areas

Mapping of limonite was based on Landsat MSS color-ratio-composite images. No limonite concentrations were found that would indicate hydrothermal alteration. Likewise, no reverse limonite anomalies were found that could be related to either hydrocarbon seepage or uranium deposition, but narrow outcrop widths, vegetation cover, and variable initial iron content in
