Crater Hill on the western side of St. Paul is one of many cones across the island. The crater is seen here from the NE. 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.
