Wrangell-Saint Elias National Park and Preserve, the largest national park within the U.S. National Park Service system, extends from the northern Pacific Ocean to beyond the eastern Alaska Range into interior Alaska. It features impressively spectacular scenery such as high and craggy mountains, active and ancient volcanoes, expansive ice fields, immense tidewater glaciers, and a myriad of alpine glaciers.

The region boasts a rich mining and exploration history prior to becoming a park in 1980. Several U.S. Geological Survey geologists have conducted reconnaissance surveys in the area since 1900. This map is the result of their work and is enhanced by more detailed investigations, which began in the late 1950s and are still continuing.

For more information about the processes that have shaped the geology of the park and a history of the geologic investigations, be sure to also check out the park's Geologic Guide.
