Overview

SDSU logo USGS Logo This high-resolution topography dataset of the southernmost San Andreas Fault (sSAF) includes a point cloud, digital surface model (DSM) and orthomosaic that cover an area of approximately 338,000 square meters along the main strand of the sSAF at Salt Creek, near the northeastern shoreline of the modern-day Salton Sea. The purpose of this dataset was to provide high-resolution imagery to examine tectonically offset geomorphic features to gather estimates for slip distribution for a study conducted along ~80 km of the sSAF
