Lake Komi was a prehistoric periglacial lake formed in the region of the present-day Russian Komi Republic when the Barents Sea outlet of the Pechora River was blocked by ice during, at least, Major glacial 4 of 4, of the Pleistocene. The latter was the last series of ice ages (glacials), which spans more than two million years.

For reference, the large moon-shaped island, top-center in the animation, is Novaya Zemlya, and the mountains to the right are the northernmost Urals. Komi Glaciology Komi
