Lake-filled Crater Hill on the western side of St. Paul is one of many craters across the island. Caribou can be seen wading along the shores of the lake. The largest of the Pribilof Islands, St. Paul consists of a 110 km2 area of coalescing small edifices with a central scoria cone. The Fox Hill lava flow at the far western end of the island is estimated to be only a few thousand years old.
