Digital geospatial data sets for two maps (Plate 1, Elk River watershed, Humboldt County, California, geologic and geomorphic features related to landsliding; and plate 2, Elk River watershed, Humboldt County, California, relative landslide potential with geologic and geomorphic features). These maps portray landslides, geomorphic features related to landsliding, relative landslide potential, geology, and stream channel geomorphic conditions in the Elk River watershed, Humboldt County, California. The GIS data are organized into four groups: landslide layers; geomorphology layers; fluvial layers; geology layers.

This collection of vector and raster data layers contain the results of landslide mapping of the Albion River Watershed, Mendocino County, California; includes geologic and geomorphic features related to landsliding and relative landslide potential.

• Preliminary map of geologic and geomorphic features related to landsliding, Jackson Demonstration State Forest, Mendocino County, California / compiled by William R. Short and Tom E. Spittler. Sheet A (black and white) and Sheet B (color).
• Preliminary map of relative landslide potential with geologic and geomorphic features, Jackson Demonstration State Forest, Mendocino County, California / compiled by William R. Short and Tom E. Spittler.
• Factors affecting landslides in forested terrain. DMG note 50.

Contains 10 vector shapefiles as well as preliminary maps of geologic and geomorphic features (landslide maps) compiled from mapping conducted between 1982 and 2001 in the Jackson Demonstration State Forest (JDSF). A preliminary map of landslide potential in the JDSF, based on landslide potential mapping conducted in 2001 in the Noyo river watershed, is included.

Contains PDF copies of the originals, as well as digital presentations of, the documents and maps produced from the Freshwater Watershed Mapping Project. These documents, Geologic and geomorphic features related to landsliding, Freshwater Creek, Humboldt County, California; and, Relative landslide potential map, Freshwater Creek, Humboldt County, California, were completed by James N. Falls in 1999 and issued as Open-file report 99-10 and 99-10a by the California Division of Mines and Geology.
