These data contain 1:24,000-scale polygons defining the extent of mapped landslides in the state of Washington. This dataset is compiled chiefly from pre-existing landslide databases created in different divisions of the Washington State Department of Natural Resources to meet a variety of purposes. Although it has been updated to include landslides from specific recent landslide events, it does not yet include landslides from recent geologic quadrangle mapping; this mapping will be included in a future release of this dataset. This dataset does not include landslides mapped at 1:100,000 scale; landslides at that scale are included in a separate geodatabase (surface_geology_100k.gdb). |
