This collection contains assorted photographs and negatives from the Space Dynamics Laboratory (SDL), primarily from the 1970s and 1980s. These images detail some of the project equipment, personnel, and locations related to SDL, and were likely collected from the office of Dr. Doran Baker, an SDL founder and professor of engineering at Utah State University. Also included are images related to Dr. Baker's other passion: the history of the western United States, particularly in areas of Cache Valley, Utah. The majority of these images are unidentified; more information will be added in the future.
