Name: Rock Fall Scarps

Display Field: ROCKFALL_ID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This is line feature class used to graphically represent the uppermost portion of a rock fall source area using the methods described in our lidar-based protocol (Slaughter and others, 2017). Only source areas visible in lidar derivative datasets and (or) aerial/orthoimagery derivative datasets are delineated with this feature class, and no rock fall scarps inferred from field reconnaissance, or other techniques are included. This feature class is part of a larger landslide inventory dataset for Washington State. Lines in this feature class are related to polygons in the ‘Rock Fall Deposits’ feature class by using the ROCKFALL_ID primary key field.
