Early exploration and name

Emlen Peaks was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos in 1960–63. It was named by the Advisory Committee on Antarctic Names (US-ACAN) after John Thompson Emlen Jr. (1908–1997), a biologist from the University of Wisconsin. As a program leader he made penguin navigational studies on the Ross Ice Shelf, the interior of Victoria Land, and elsewhere in Antarctica in 1962–63.

Main article: Gressitt Glacier

71°30′S 161°15′E. A broad glacier, about 45 mi long, draining the area between Daniels Range and Emlen Peaks in the Usarp Mountains and flowing northeast to enter the Rennick Glacier just north of the Morozumi Range. Mapped by USGS from surveys and U.S. Navy air photos, 1960–63. Named by US-ACAN for biologist J. Linsley Gressitt, Program Director who made biological studies, particularly in the Ross Sea area, in six austral summers, 1959–60 to 1965–66.
