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.

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.
