It was discovered by members of the United States Antarctic Service (USAS) on aerial flights in 1940, and named for Jacob Bursey, member of the Byrd Antarctic Expedition (1928–30) and dog-driver with the USAS party which sledged to the west end of the Flood Range in December 1940.[1]
Volcanism
editMount Bursey consists of two coalescing shield volcanoes, namely Hutt Peak and Koerner Bluff. Each shield contains a 4–5 km (2.5–3.1 mi) diameter caldera at its summit. Potassium–argon dating has indicated both shields formed during the Miocene epoch, with volcanism at Hutt Peak occurring as recently as 0.49 million years ago.[2]
Starbuck Crater is a volcanic cone on the mountain.
