Aniakchak is an enormous volcanic crater, six miles in diameter, created by the collapse of a 7,000-foot volcanic mountain. A relatively recent cone has developed inside the crater. This cone, called Vent Mountain, reaches 3,350 feet. Aniakchak Peak, the summit of the mountain, is a high peak on the crater's south rim, over 1000 feet above the crater floor. Lava flows, cinder cones, and exploding pits, not to mention a rich variety of plant and animal life, can all be seen in the area, all within the Aniakchak National Monument and Preserve. The park lies 450 miles south of Anchorage on the roadless Alaska Peninsula, and is one of the wildest and most remote areas in Alaska. Weather can be severe throughout the year. Approach is either on foot from Port Heiden or, more typically, by float plane from King Salmon.
