Landslide Inventory Polygons depicts landslide activity and debris flows at scales of 1:24,000 or better and were captured using LiDAR, stereo aerial photography, other data, and field reconnaissance by the UGS. Landslide Inventory Polygons represents the most recent landslide mapping efforts of the UGS, and when possible should be used first.

Landslide depositions throughout Utah at a variety of scales and accuracies. This dataset represents a compilation of digitizing efforts by the Utah Geological Survey (UGS), and is not new landslide-specific mapping. Landslides were compiled from all known pre-1989 published and unpublished references available at the time, additional landslide paths were later added from 1989-2007 geologic maps and UGS landslide investigations.
