Peter Glacier is a short, broad glacier draining northeast into Jutulstraumen Glacier just east of Neumayer Cliffs and Melleby Peak in Queen Maud Land.

Named for Peter Melleby who was in charge of sledge dogs with the NBSAE.
Mosby Glacier is a glacier 5 nautical miles (9 km) wide at its mouth, flowing in a southeasterly direction to the northwest corner of New Bedford Inlet, on the east coast of Palmer Land, Antarctica. It was discovered and photographed from the air in December 1940 by the United States Antarctic Service. During 1947 it was photographed from the air by the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) mapped its terminus from the ground. It was named by the FIDS for Hakon Mosby, a Norwegian meteorologist and oceanographer.
