Surficial geologic maps along riparian zone of Animas River and headwater tributaries, Silverton to Durango, Colorado

Sixteen primary units were mapped that included human-related deposits and structures, eight alluvial deposits, four colluvial deposits, one glacial deposit, one travertine deposit, and undifferentiated bedrock. Each of the surficial geologic strip maps has .PDF links to surficial geology photographs, which enables the user to take a virtual tour of these deposits. Geochemical data collected from mapped surficial deposits that pre-date and post-date mining activity have aided in determining the geochemical baseline in the watershed.

Several photographs with their corresponding geochemical baseline profiles are accessible through .PDF links from several of the maps. A single coverage for all surficial deposits mapped is included as an ArcInfo shape file and as an Arc Export format .e00 file. This product consists of one vector coverage.

This coverage is that of the surficial deposits mapped along the riparian zone of the Animas River from its headwater tributaries above Silverton to Durango, Colo.
