Mjell Glacier is a glacier 9 nautical miles (17 km) long, flowing northeast between Mount Bergersen and Isachsen Mountain in the Sør Rondane Mountains of Antarctica. It was mapped by Norwegian cartographers in 1957 from air photos taken by U.S. Navy Operation Highjump in 1946–47, and named "Mjellbreen".
The Mistichelli Hills are a group of moderately low, rocky coastal hills, 1 nautical mile (2 km) southwest of the McKaskle Hills, on the eastern margin of the Amery Ice Shelf, Antarctica.

Mistichelli, an air crewman on Operation Highjump photographic flights over the area.
Litz Glacier is a glacier flowing northeast from the vicinity of Smith Peak and Litz Bluff in north-central Thurston Island, Antarctica.

Hjelmkalven Point is a rocky point on the north side of Vesthjelmen Peak, at the east side of the mouth of Byrdbreen in the Sør Rondane Mountains of Antarctica. It was mapped by Norwegian cartographers in 1946 from air photos taken by the Lars Christensen Expedition, 1936–37, and in 1957 from air photos taken by U.S. Navy Operation Highjump, 1946–47. It was named Hjelmkalven by the Norwegians.
