From the Author’s notes:
The Mt. Sopris Quadrangle covers an area of the Crystal River valley extending south of the town of Carbondale to the mouth of Avalanche Creek. Mapping of this quadrangle has contributed to further understanding of the Neogene salt related deformation and geomorphology in an area of active salt tectonism. It also contains new data on the intrusive history of the Middle Tertiary Mt. Sopris stock, including six whole-rock and trace element analyses. Of interest, it contains Holocene and late Pleistocene glacial, periglacial, and rock-glacial deposits.
