Lizard Nunatak ( 69°30′S71°3′W / 69.500°S 71.050°W / -69.500; -71.050 Coordinates: 69°30′S71°3′W / 69.500°S 71.050°W / -69.500; -71.050 ) is a nunatak rising to about 800 metres (2,600 ft) situated within the Nichols Snowfield, in the northern portion of Alexander Island, Antarctica. It is situated 12 km east by north of Mount Kliment Ohridski and 9 km south-southeast of the summit of Landers Peaks in Sofia University Mountains, and 6.4 km southwest of Serpent Nunatak and 9.38 km north by west of Tegra Nunatak in Rouen Mountains. The feature was so named by the UK Antarctic Place-Names Committee in 1977 from its shape and in association with Serpent Nunatak lying to the northeast. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Nichols Snowfield is a snowfield, 22 nautical miles (41 km) long and 8 nautical miles (15 km) wide, bounded by the Rouen Mountains and Elgar Uplands to the east and Lassus Mountains to the west, in the north part of Alexander Island, Antarctica. The snowfield was first sighted from the air and roughly mapped by the British Graham Land Expedition (BGLE) in 1937. Mapped in detail from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the RARE for Dr. Robert L. Nichols, head of the Department of Geology, Tufts University, and senior scientist of the Ronne expedition.
