Dater Glacier

Location of Sentinel Range in Western Antarctica.

Sentinel Range map

The Dater Glacier is a steep valley glacier in Antarctica, 24 miles (39 km) long and from 1 to 3 miles (2 to 5 km) wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.

The glacier was discovered by U.S. Navy Squadron VX-6 on photographic flights of Deccember 14–15, 1959, and mapped from these photographs by the United States Geological Survey. It was named by the Advisory Committee on Antarctic Names after Henry M. Dater, a historian on the staff of the U.S. Antarctic Projects Officer and the U.S. Naval Support Force Antarctica.
