<br><dl><dd><b>Location</b> Aniakchak National Monument and Preserve</dd>
<dd><b>Description</b>  Given its remote location and notoriously bad weather, Aniakchak is one of the least visited units of the National Park System. A vibrant reminder of Alaska's location in the volcanically active "Ring of Fire," the monument is home to an impressive six-mile wide, 2,500 ft. deep caldera formed during a massive eruption 3,500 years ago</dd></dl>
