Photo Gallery

Lake-filled Crater Hill on the western side of St. Paul is one of many craters dotting the island. Reindeer (caribou) can be seen wading along the shores of the lake. St. Paul is the largest of the Pribilof Islands and consists of a 110 sq km area of coalescing small basaltic shield volcanoes capped by a central cinder 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 is one of many pyroclastic cones dotting the island. The crater, which contains an elongated lake, is seen here from the NE. St. Paul, the largest of the Pribilof Islands, consists of a 110 sq km area of coalescing small basaltic shield volcanoes capped by a central cinder cone. The Fox Hill lava flow at the far western end of the island is estimated to be only a few thousand years old.

A Space Shuttle image of St. Paul Island shows Northeast Point at the upper right, Reef Point at the bottom-center, and Southwest Point at 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 sq km island is the largest of the Pribilof Islands and contains more than a dozen basaltic cinder cones and associated lava flows.
