Name: Recent Landslides

Display Field: RECENT_LS_ID

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This is a point feature class used to define the approximate head scarp or initiation area of landslides using the methods described in our lidar-based protocol (Slaughter and others, 2017). Recent landslides visible in aerial/orthoimagery, from field reconnaissance, or from information from outside sources are defined with this feature class. This feature class is part of a larger landslide inventory dataset for Washington State.
