He worked with a team that was analyzing lunar features in an attempt to establish a relative time framework for the moon. This research, supported by NASA, resulted in the publication of six papers on lunar stratigraphy. He was proud of this research and believed that the experience helped hone his skills as a stratigrapher. Doug moved to Denver, Colorado in 1974 to work for Chevron Oil Company. Four years later he accepted a position as a Research Geologist with the US Geological Survey (USGS) in Denver. He worked in the Paleontology and Stratigraphy Branch of the USGS until he retired in 2006.
