Aniachak National Monument and Aniachak National Preserve by National Parks Service

Looking into the Caldera from The Gates, Troy Hamon, NPS Chief of Resource Management Aniakchak Caldera is a raw and rugged volcanic feature laying in a landscape that is, because of its remoteness, little affected by human occupancy. Plant and animal communities are in tune with the natural phenomena that control their habitat. Volcanic activity has subsided since the last eruption in 1931, but the geologic processes that follow such activity continue to weather, erode, and redistribute the volcanic materials. Hot spots and warm springs on the caldera floor indicate that eruptive activity may resume at any time.
