Located on the Alaska Peninsula, 450 miles southwest of Anchorage, Aniakchak National Monument and Preserve is inaccessible by road. Notoriously bad weather makes access to Aniakchak unpredictable. Drop-offs and/or pick-ups may be significantly delayed.

The outlet of the Aniakchak River, referred to as "The Gates," was formed when water within the caldera breached the rim and carved through the wall. Terrace deposits above the current water level of Surprise Lake indicate that the lake once filled 50 percent more of the caldera.
