Located in the preserve's northwest region, maar lakes are some of the most significant features of Bering Land Bridge National Preserve. Ranging in diameter from 13,000-26,000 feet, with depths approaching 1,000 feet, these maar lakes are the largest in the world. They were created from giant explosions as magma from a volcano came in contact with permafrost. Later they filled with rain water and snowmelt. They can be accessed by float plane (lake landings), by non-motorized vehicle, by foot, or, during the winter, by snowmachine. Outdoor activities include scenic viewing, photography, and hiking along the shoreline of the lakes.
