  1. Title: Relative Landslide Potential Matrix: Albion River Watershed, California, 1984-2002

    Contributors:

    Summary: This raster layer represents relative landslide potentials within the Albion River watershed in Mendocino County, California. These data were generated using a landslide potential matrix prepared by geologists familiar with the study area. The matrix is based on landslide feature type and activity, geomorphic features, geology, and slope found within the watershed. The matrix is included in the data dictionary with the relative landslide potential layer information. This mapping began as part of the North Coast Watershed Assessment Program (NCWAP) which was de-funded by the Legislature in June 2003, the work was subsequently completed in late 2003 and early 2004. The California Geological Survey (CGS) evaluated the geology, fluvial geomorphic characteristics, relative slope stability and geomorphic characteristics within the watershed, and compiled the digital geospatial data described in this document. This mapping and compilation is geared toward providing baseline geologic and geomorphic data to aid in responsible land management, as well as the development of watershed restoration projects, watershed management strategies, and watershed plans. California. Division of Mines and Geology. (2004). Relative Landslide Potential Matrix: Albion River Watershed, California, 1984-2002. California Division of Mines and Geology. Available at: http://purl.stanford.edu/sd935db0706 The Albion River watershed is predominantly located on the coastal side of the Mendocino Range, the western-most range of the northern California Coast Ranges Geomorphic Province. The Albion River drains 43 square miles of the Mendocino County coastline. The headwaters are approximately 12 miles inland. The data is a product of the Department of Conservation, California Geological Survey’s (CGS) investigation of landslides and fluvial geomorphology of the Albion River watershed. The investigation was based on interpretation of 1984 and 2000 aerial photos, findings from CGS’s landslide mapping conducted in the early 1980s (Kilbourne, R.T. 1982-84, Manson, M. W. 1984), as well as other sources (McLaughlin, 1997 and Matthews, 2001).

The Noyo River Watershed lies within the Coast Ranges physiographic province of California. The area is mountainous, with elevations ranging from sea level in the coastal area of the watershed to approximately 2,850 feet in the eastern headwaters portion of the watershed. The majority of the watershed is heavily forested; portions of the extreme western and southeastern portions of the watershed are grass covered.
