In May 1867, he was appointed assistant geologist under Clarence King on the Geological Exploration of the 40th Parallel and in July 1879 became geologist in charge of the Coloradodivision of the USGS. His position at the USGS led to several studies and publications on mining regions in the west including Leadville and also a major study of the Denver Basin which was completed in collaboration with Cross, Eldridge, Homans, Talmadge and Marsh. Emmons provides an overview of the geology, stratigraphy, and structural geology of the region. Eldridge describes the Mesozoic geology, Post-Laramie and Tertiary geology. Cross provides some of the earliest stratigraphic details and also describes the igneous geology and petrography. Eldridge provides details on the economic geology and hydrology. Knowlton provides some of the first descriptions on fossil plants and O. C. Marsh provides a detailed systematic study on newly discovered Jurassic and Cretaceous vertebrate fossils. The publication was hailed as a major advancement to our knowledge of the geology of the region.
