Mount Aniakchak is a 3,400 year old volcanic caldera located in the Aleutian Range of Alaska, USA. It has a diameter of about 10 kilometres (6 miles). Within the caldera are several examples of lava flows and cinder cones, as well as a body of water known as Surprise Lake.

The area around the volcano is the Aniakchak National Monument and Preserve, all of which is part of the Pacific Ring of Fire. The caldera itself and the surrounding area can be observed free of geometric distortion as the image has been orthorectified.
