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.

Crater Hill, on the western side of St. Paul Island, is one of many cones on the 110 km2 island. The complex crater is 200 m deep and has several smaller cones within it, as well as a 50-m-thick lava flow.

A Space Shuttle image of St. Paul Island shows Northeast Point to the upper right, Reef Point at the bottom-center, and Southwest Point to the left. Snow-covered Big Lake lies SW of Northeast Point, Bogoslof Hill near the center of the island, and Rush Hill is the cone along the NW coast. Rush Hill produced lava flows from NE-trending fissures. The 110 km2 island is the largest of the Pribilof Islands and contains more than a dozen scoria cones and associated lava flows.

St. Paul island, one of the Pribilof Islands in the Bering Sea, is composed of overlapping scoria cones, spatter cones, and lava flows, shown in this October 2017 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 23 km across). Cones include the westernmost Rush hill, Black Bluffs scoria cone on the southern peninsula, the Bogoslof Hill complex in the center, and North Hill along the northern coastline.
