Location

Danco Coast, Antarctic Peninsula. Hughes Bay near the northeast end

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.

Western features

Features of the west (left) side include, from south to north:

Obretenik Bastion

64°29′38″S 60°59′55″W An ice-covered buttress rising to 1,932 metres (6,339 ft) high at the northeast extremity of Herbert Plateau. Situated between upper Blériot Glacier and upper Cayley Glacier, 10 kilometres (6.2 mi) south of Mount Morton, 14.45 kilometres (8.98 mi) southwest of Mount Berry. Steep and partly ice-free west, north and east slopes. Named after the settlement of Obretenik in Northeastern Bulgaria.

REMA Explorer

The Reference Elevation Model of Antarctica (REMA) gives ice surface measurements of most of the continent. When a feature is ice-covered, the ice surface will differ from the underlying rock surface and will change over time. To see ice surface contours and elevation of a feature as of the last REMA update, Open the Antarctic REMA Explorer Enter the feature's coordinates in the box at the top left that says "Find address or place", then press enter The coordinates should be in DMS format, e.g. 65°05'03"S 64°01'02"W. If you only have degrees and minutes, you may not be able to locate the feature. Hover over the icons at the left of the screen Find "Hillshade" and click on that In the bottom right of the screen, set "Shading Factor" to 0 to get a clearer image Find "Contour" and click on that In the "Contour properties" box, select Contour Interval = 1m You can zoom in and out to see the ice surface contours of the feature and nearby features Find "Identify" and click on that Click the point where the contour lines seem to indicate the top of the feature The "Identify" box will appear to the top left. The Orthometric height is the elevation of the ice surface of the feature at this point.
