Preliminary interpretation of pre-2014 landslide deposits in the vicinity of Oso, Washington
Ralph A. Haugerud
2014, Open-File Report 2014-1065
High-resolution topographic surveys allow fairly precise mapping of landslide deposits and their relative ages. Relative ages are determined by cross-cutting relations and the amount of smoothing—more smoothed slide deposits are older—of these deposits. The Tulalip Tribes, in partnership with the Puget Sound Lidar Consortium, acquired a high-resolution lidar (light detection...
