Jennings Promontory

Jennings Promontory () is a prominent rock promontory on the eastern margin of Amery Ice Shelf between the Branstetter Rocks and Kreitzer Glacier.

Exploration

Jennings Promontory was delineated in 1952 by John H. Roscoe from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by him for Lieutenant Joe C. Jennings, United States Navy, co-pilot and navigator on Operation Highjump photographic flights in this area.

Location

Jennings Promontory defines the western end of the Ingrid Christensen Coast, which extends east to the West Ice Shelf.
It is northeast of Gillock Island, north of the Reinbolt Hills and Linton-Smith Nunataks, and south of the Mistichelli Hills, McKaskle Hills and Statler Hills.
The promontory is a bedrock outcrop in a region of Cambrian charnockite surrounded by high-grade metamorphic rocks.
