Landslide Inventory Polygons depict 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.

Data represents a compilation of existing mapping of landslides at 1:100,000 pre 2007, and new landslide specific data depicting a more detailed inventory at 1:24,000 post 2008.
