At MGS, he authored many publications about the ground water resources of Missouri, and testified as an expert witness in the Times Beach hearings about dioxin contamination of the water supply. Upon his retirement from MGS, he and Amy moved to Estes Park where they had spent many summer vacations as a family.

He enjoyed being the "resident geologist" and meeting visitors from around the world. Don was always interested in the history of the Old West, particularly mining. He excelled at many avocations including watercolor painting of cowboys and western scenes, lost wax casting of belt buckles, and Hopi Kachina carving.
