Abstract

We present new data describing relict periglacial landforms preserved in the interior Great Basin of the southwestern United States. This summary is significant because a thorough understanding of the occurrence and spatial distribution of these landforms is still lacking after 60 years of geomorphic studies in this region. This is largely because many landforms are often un-recognized and because many mountains in the Great Basin are remote and offer poor access. To help address this knowledge gap, we use a GIS with high-resolution imagery and field mapping to identify and describe features that indicate a locally extensive periglacial environment existed in the Snake Range of east-central Nevada during the Late Quaternary. We also compare the location of these landforms with solar radiation models produced using ESRI's Solar Analyst to evaluate the efficacy of using solar modeling as means to predict suitable field sites for periglacial landforms. This simple modeling technique accurately identifies the location of known periglacial landforms in the Snake Range and therefore we believe it could be used to prioritize sites of interest throughout the Great Basin.
