USGS Topo · Published 1972About this map
The Aniakchak Crater dominates this 1963 survey, revealing a landscape defined by volcanic activity in the Aleutian Range. At the heart of the caldera lies Surprise Lake, the source of the Aniakchak River, which breaches the crater wall through a narrow passage known as The Gates. Internal features like Vent Mtn and Half Cone illustrate the secondary eruptions that have shaped the crater floor, while the surrounding rim is marked by prominent high points such as Aniakchak Peak and Black Nose.
