Copperstain Ridge [SEP] continent
Copperstain Ridge
Copperstain Ridge () is a ridge about long which descends north-northeast from Mount Freed, in the Bowers Mountains, a major mountain range situated within Victoria Land, Antarctica. The feature was so named by the New Zealand Geological Survey Antarctic Expedition, 1967–68, because of the extensive, ductile metal, copper staining protruding outward from the edges of the ridge. The ridge lies on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Named by Advisory Committee on Antarctic Names (US-ACAN) for Captain Frank H. Radspinner, Jr., USA, commanding officer of the helicopter detachment that supported the United States Geological Survey (USGS) Topo East-West party that surveyed this area in 1962–63.
