Harrow Peaks

The Random Hills (74°7′S 164°25′E / 74.117°S 164.417°E / -74.117; 164.417 (Random Hills)) are a group of rugged hills in Victoria Land, Antarctica. They are bounded on the west by Campbell Glacier and on the east by Tinker Glacier and Wood Bay. They are centered about 15 nautical miles (28 km; 17 mi)) north-northwest of Mount Melbourne.

Exploration and name

The Random Hills were named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1966–67, because of the random orientation of the ridges which comprise the feature.

Geology

The Random Hills are part of the Melbourne Volcanic Province of the McMurdo Volcanic Group. K–Ar or Rb–Sr dating has given ages of 12.63 ± 0.17 million years and 12.43 ± 0.16 million years for Random Hills hawaiite.

Location

The Random Hills lie between the Tinker Glacier Tongue to the east, Baker Rocks on the Mount Melbourne peninsula to the south, and Bier Point and the Campbell Glacier to the west. The Burns Glacier separates the hills from Pinckard Table to the east. The Clausnitzer Glacier flows eastward through the hills to join the Tinker Glacier.
