Paine Ridge
The Morozumi Range () is a mountain range in the Usarp Mountains of North Victoria Land, Antarctica. It extends northwest–southeast for , with its northern elevations overlooking the convergence of Gressitt Glacier and Rennick Glacier. Early exploration and name The Morozumi Range was mapped by the United States Geological Survey from surveys and United States Navy air photos in 1960–63. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Henry M. Morozumi, an aurora scientist at South Pole Station in 1960, and Station Scientific Leader at Byrd Station in 1963. Geology The Morozumi Range is in the Rennick Graben, separated by the Rennick Faults from the Wilson Group rocks of the USARP mountains. Basement rocks are low-grade metasedimentary rocks that include greywacke-shale. The northern end holds the Adamellite Massif, a pluton of Granite Harbour Intrusives. Glaciers Gressitt Glacier .

Usarp Mountains
The Usarp Mountains are a major Antarctic mountain range, lying west of the Rennick Glacier and trending north to south for about . The feature is bounded to the north by Pryor Glacier and the Wilson Hills. These mountains were discovered and first photographed from aircraft of the U.S. Navy Operation Highjump in 1946. They were first sighted and entered by the U.S. Victoria Land Traverse 1959-1960 (VLT), and the first ascent of Mount Welcome was made by John G. Weihaupt, Alfred Stuart, Claude Lorius, and Arnold Heine of that traverse team. The mountains were completely mapped by the United States Geological Survey from VLT reports, U.S. Navy air photos from 1960–63, and subsequent surveys. The name is an acronym of the United States Antarctic Research Program (USARP), and was applied by Advisory Committee on Antarctic Names (US-ACAN) in recognition of the accomplishments of that program in Antarctica.
