Parts of Wyoming have some of the highest landslide densities in the United States. Every year landslides occur in Wyoming, with some causing significant damage or disruption to daily activities

These web pages have been generated for two reasons. The first of these is to increase awareness of landslides in Wyoming. The second is to provide citizens with a means to access current landslide data for the state.

The landslides were mapped over a 15-year period by the Geologic Hazards Section of the Wyoming State Geological Survey. Over 850 7.5-minute quadrangles have been mapped for landslides. The Wyoming State Geological Survey (WSGS) and the Water Resources Data System (WRDS) are in the process of generating coverages of them for Wyoming.
