The Ukinrek Maars were formed during an eruption in 1977 at a Bering Sea lowland area without previous volcanic activity. Powerful phreatomagmatic explosions formed the 170-m-wide West Maar and 300-m-wide East Maar. The maars were named from the Yupik Eskimo words for "two holes in the ground." Late in the 10-day-long eruption a lava dome formed in East Maar, seen here from the NW rim with Peulik volcano in the background. The dome is now submerged beneath a 60-m-deep lake.
