It is surrounded by steep cliffs and consists mostly of lava flows and scoria, subdivided in two geological units. Bridgeman Island is the emergent portion of a larger volcano in the Bransfield Strait, which contains numerous volcanoes including Deception Island and numerous seamounts. The island formed during the Pleistocene; there is evidence of an eruption in 1821 that generated a probable tuff cone west of Bridgeman Island, which has now disappeared.
