Convoy Range

[1] It is a peneplain, with an early Paleozoic granitic basement covered in sedimentary and igneous rocks from the Permian–Triassic to the Jurassic.

The New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) worked in this area in 1957.

[2] The Evans Piedmont Glacier on the Ross Sea coast lies to the east of the range.

[2] The region covered by the Convoy Range and Franklin Island to the east has a granitic basement from the early Paleozoic, made up of large bodies of the Granite Harbour Igneous Complex formed in the late Cambrian or early Ordovician, containing small bodies of Wilson Terrane metamorphic rocks.

The Wilson Terrane rocks are inferred to be from the Precambrian or Cambrian, deformed and metamorphosed in the Ross Orogeny of the early Paleozoic.

The area was uplifted and eroded into a peneplain after the Ross Orogony, and was covered with sandstones of the Beacon Supergroup.

A lobe of the Northwind Glacier flows a short distance west into the mouth of the valley.
