Erosion of unwelded pyroclastic flow deposits from Kurile Lake caldera formed these cliffs along the Ukanovich River, 10 km N of the caldera. Voluminous pyroclastic flows accompanying formation of the caldera about 7,600 years ago covered the area during one of the largest Holocene eruptions of the Kamchatka Peninsula.
