Head Scarp Boundary for the Landslides in the Little North Santiam River Basin, Oregon

Polygons represent head scarps and flank scarps associated with landslide deposits in the
Little North Santiam River Basin, Oregon.
This work was completed as part of the Master's thesis "Turbidity Monitoring and LiDAR
Imagery Indicate Landslides are Primary Source of Suspended-Sediment Load in the Little
North Santiam River Basin, Oregon,
Winter 2009-2010" by Steven Sobieszczyk, Portland State University and U.S. Geological
Survey.
Data layers in this geodatabase include: landslide deposit boundaries (Deposits); field-verfied
location imagery (Photos); head scarp or scarp flanks (Scarp_Flanks); and secondary scarp
features (Scarps).The geodatabase template was developed by the Oregon Department of
Geology and Mineral Industries (Burns and Madin, 2009).
