Bridgeman Island Volcano | John Seach


South Shetland Islands, Antarctica

62.05 S, 56.75 W
summit elevation 240 m

Bridgeman Island is located 100 km off the northern tip of the Antarctic peninsula.

The island measures 900 m by 600 m, and is the remnant of a much larger volcanic edifice, eroded and now submerged beneath the sea. The summit is covered in snow and inclined to SE. A crater is located at an elevation of 27 m in the west of the island.

Pyroclastic deposits on Bridgeman are a bright brick-red colour due to intense hydrothermal activity. Active fumaroles were reported on the island between 1821 and 1850.
