Lava dome remnants from four historical eruptions can be seen in this NW-looking aerial view of Bogoslof in the Aleutians. The pinnacle to the left is Castle Rock, a remnant of a 1796 lava dome. The circular, flat-topped area to its right is a remnant of a 1927 lava dome. An eruption in 1992 produced the light-colored rounded lava dome forming upper right part of the island. The island to the upper right formed in 1883. Photo by John Sease, 1998 (NMS/NOAA).
