The Traffic Circle (English for roundabout ) is an icy and 500  m high plateau in Grahamland in the center of the Antarctic Peninsula . It is located south of Mount Ptolemy halfway between Marguerite Bay in the west and Mobiloil Inlet in the east.

In its center, from which five glacier troughs extend radially like the spokes of a wheel, rises the Hub Nunatak . The trough going to the north is connected to the Gibbs and Neny glaciers or further with the Neny Fjord , the one going west to the Lammers glacier and the Windy Valley and also to the Mikkelsen Bay . Another “spoke” is the Cole Glacier , which is connected to the Wordie Ice Shelf to the southwest along the Godfrey Upland . The Weyerhaeuser Glacier, on the other hand, flows south in the direction of the Wakefield Highland and is connected to a glacier system that drains to the Wordie Ice Shelf. The last of the group is the Mercator Piedmont Glacier , which is fed by the Weyerhaeuser, Cole and Gibbs glaciers and widens into the Mobiloil Inlet.

This large network of glaciers was discovered by the East Base team stationed on Stonington Island for the United States Antarctic Service Expedition (1939–1941), who used it as a transport route to explore the highlands on the Antarctic Peninsula and named it based on it.
