Exploration and naming

The Lyttelton Range was mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960-63. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after the port of Lyttelton, New Zealand, where over the years, many expedition ships refueled and replenished supplies en route to Antarctica; also in recognition of the friendship and cooperation of its citizens with American participation in the U.S. Antarctic Research Program.^[1]

Location

The upper Dennistoun Glacier flows past its east side.^[2] The Atkinson Glacier flows between Findlay Range and the west side of Lyttelton Range, flowing northward into Dennistoun Glacier.^[3]
