# Cayley Glacier

The Cayley Glacier (64°20′00″S 60°58′00″W﻿ / ﻿64.33333°S 60.96667°W﻿ / -64.33333; -60.96667﻿ (Cayley Glacier)) is a glacier flowing northwest into the south side of Brialmont Cove, on the west coast of Graham Land, Antarctica.

## Location

Cayley Glacier terminates on the Danco Coast of the Antarctic Peninsula, on the west side of Graham Land. It flows north from the south end of the Detroit Plateau and the north end of the Herbert Plateau into Hughes Bay, which opens onto the Gerlache Strait. Baldwin Peak is a prominent feature of the east side of te glacier. It is joined from the right (east) by the Mouillard Glacier at its mouth.

## History

Cayley Glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition (FIDASE) in 1956–57 and mapped from these photos by the Falkland Islands Dependencies Survey (FIDS). It was named by the UK Antarctic Place-Names Committee (UK-APC) in 1960 for Sir George Cayley (1773–1857), English engineer, the "father of aeronautica," who first defined the main principles of mechanical flight, 1796–1857, and also designed the first caterpillar tractor in 1826.
