The Hadley Upland is a triangular-shaped remnant of a wave-shaped plateau of up to 1900 m height in south-central Grahamland on the Antarctic Peninsula . It is bounded by the Windy Valley , Martin , Gibbs, and Lammers Glaciers .
The highlands have been known since the US polar explorers Finn Ronne and Carl R. Eklund (1909-1962) traveled over the Lammers and Gibbs glaciers as part of the United States Antarctic Service Expedition (1939-1941) in January 1941 . During the Ronne Antarctic Research Expedition (1947–1948) the first aerial photographs were taken in 1947. The Falkland Islands Dependencies Survey carried out surveys between 1948 and 1950 and again in 1958. The UK Antarctic Place-Names Committee named it on August 31, 1962 after the English mathematician and astronomer John Hadley (1682-1744), who at the same time as the American inventor Thomas Godfrey (1704-1749), but independently of this , developed a quadrant (a precursor to the sextant ) in 1730 .
