The planet's southernmost active volcano, Erebus (), as well as the dormant volcano Terror (), are situated on the island. They were named by Captain James Ross after his ships HMS Erebus and HMS Terror. The third highest elevation is Mount Bird, with Shell Glacier and Endeavour Piedmont Glacier on its slopes. Abbott Peak stands between Mount Erebus and Mount Bird. Gamble Cone and Kyle Cone stand in the east of the island. Beeby Peak is 2.4 nautical miles (4.4 km) east-northeast of the summit of Mount Bird.
