The Ukinrek Maars are two phreatomagmatic vents that formed on the north side of the Aleutian Range on a low area bordering the Bering Sea. The maars are 1.5 km south of Becharof Lake and 12 km northwest of Peulik Volcano. The western of the two is elliptical in shape and up to 170 m in diameter and 35 m deep. The east maar lies 600 m to the east and is circular and up to 300 m in diameter and 70 m deep. The east maar has a 49 m-high lava dome within the crater lake.
