Mountain Ascended
Petermann Peak
Petermann Peak is a dramatic 2,943-metre (9,656 ft) glaciated nunatak dominating western Fraenkel Land and the inner Kejser Franz Joseph Fjord in Northeast Greenland. Discovered in August 1870 by Julius Payer and named after German cartographer August Petermann, the mountain was long believed to be the highest summit in all of Greenland until the Watkins Range was surveyed. On August 15, 1929, Scottish polar geologist James Wordie led the Cambridge Expedition to its maiden first ascent via the Gregory Glacier. Standing within the Northeast Greenland National Park, Petermann Peak is an iconic monument of high-latitude Arctic mountaineering.

On August 15, 1929, Scottish polar geologist James Wordie and his Cambridge University team completed the historic maiden first ascent of Petermann Peak (2,943 m) in Northeast Greenland. Long presumed to be the highest mountain on the island, the nunatak was conquered via the heavily crevassed Gregory Glacier and a rugged mixed ridge in pristine Arctic weather.
