The combination of steep slopes and high precipitation make landslides a very common natural hazard in the Pacific Northwest and lidar is a very valuable tool in mapping past landslides and identifying future landslide hazards. Below are several lidar-derived maps and images of landslides made to support Washington Geological Survey's Landslide Hazards Program
