Summary: This layer is a georeferenced raster image of the historic paper map entitled: Victoria mining districts, mining divisions & the gold fields, engraved by William Slight under the direction of R. Brough Smyth ; colored by Arthur Everett, August 1st, 1868. It was published by Dept of Mines ca. 1868. Scale [ca. 1:1,000,000].The image inside the map neatline is georeferenced to the surface of the earth and fit to the coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, administrative boundaries, railroads, gold reefs, mining districts, telegraph lines, shoreline features, and more. Relief shown by hachures. Includes notes.This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

Title: 10-Meter Digital Elevation Model: Albion River Watershed, California, 1984-2002
Contributors:- Raster data
- 2004
Summary: This raster layer is a 10-meter resolution digital elevation model (DEM) depicting the terrain surface and elevations within the Albion River watershed. These data were generated from 7.5-minute topographic quadrangle maps by the US Geological Survey. 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). 10-Meter Digital Elevation Model: Albion River Watershed, California, 1984-2002. California Division of Mines and Geology. Available at: http://purl.stanford.edu/jg941rj5247 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).
