Surficial geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado

This data release presents geologic map data for the surficial geology of the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado, and an adjacent area to the north of the Blanca Peak quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains Province, and the Great Plains Province, Raton Section. Geologic mapping is mostly compiled from published geologic map data sources ranging from 1:24,000 to 1:250,000 scale, with limited new interpretive contributions. Gaps in map compilation are related to a lack of published geologic mapping at the time of compilation, and not necessarily a lack of surficial deposits. Much of the geology incorporated...
