Wargentin - 85 km wide
(Click on the image for a larger view, then click "BACK")
Here is a strange crater. Long after it was formed Wargentin was filled to the brim with runny lava that seeped in through cracks in the crater floor. With no breaks in the crater's wall, the lava rose up to nearly the top. As a result, Wargentin is not really a crater - it is more like a plateau. Wargentin rises about 300 meters above its surroundings.
