Bear Peninsula [SEP] continent
Bear Peninsula
Bear Peninsula () is a peninsula about 80 km (50 mi) long and 40 km (25 mi) wide which is ice covered except for several isolated rock bluffs and outcrops along its margins, lying 48 km 30 mi) east of Martin Peninsula on Walgreen Coast, Marie Byrd Land, Antarctica.
First delineated from aerial photographs taken by USN Operation Highjump in January 1947. Named by US-ACAN after the ice-ship "USS Bear", flagship of
of the continent, while Kodiak bears descend from broad-skulled bears from Kamchatka, which colonized the Alaskan peninsula. Brown bear fossils discovered in Ontario, Ohio, Kentucky and Labrador show the species occurred farther east than indicated in historic records. In North America, two types of the subspecies "Ursus arctos horribilis" are generally recognized—the coastal brown bear and the inland grizzly bear; these two types broadly define the range of sizes of all brown bear subspecies.
