The steep Bridgeman Island, seen here from the SE, is a 600 x 900 m remnant of a much larger volcanic edifice that is mostly submerged. The base displays bedded pyroclastic rocks, and an erosional surface cut into these rocks is filled by horizontal lava flows (left center). The extensively eroded island does not display youthful volcanic features.
