In 1890, geologist Harry Fielding Reid, A&S 1880, 1882 (PhD), discovered—and proudly named—the Johns Hopkins Glacier in Alaska's Glacier Bay. He also named a smaller one for Daniel Coit Gilman

Johns Hopkins Glacier is a 12-mile-long (19 km) glacier located in Glacier Bay National Park and Preserve in the U.S. state of Alaska. It begins on the east slopes of Lituya Mountain and Mount Salisbury, and trends west to the head of Johns Hopkins Inlet, 1 mile (1.6 km) southwest of the terminus of Clark Glacier and 79 miles (127 km) northwest of Hoonah.
