J. D. (John David) Love

Raised on a ranch in central Wyoming, J. D. Love became one of the American West’s best-known field geologists. He studied at the University of Wyoming and Yale, then spent much of his career with the U.S. Geological Survey, building a reputation for careful work on the geology of Wyoming and the Rocky Mountains.

Love was especially known for mapping large regions of Wyoming and for explaining complex landscape history in a way general readers could follow. He wrote and co-wrote many scientific papers, maps, and books, including work on Grand Teton National Park, and his long experience in the field made him an important guide to the region’s deep past.

He is also remembered as a conservation-minded scientist whose life and work were closely tied to Wyoming. Accounts from archives, historians, and later writers describe him as a major figure in understanding the land, fossils, and mountain geology of the state.
