Aniakchak National Monument & Preserve

National park units in Alaska precede the establishment of the National Park Service in 1916. The first park unit, Sitka National Monument, was conceived in 1908, and by the mid-1920s four national monuments along with Alaska’s first national park were part of the growing park system. Discover how the early 1900s and observations of a few helped to establish the National Park Service in Alaska.

In Alaska, small planes are often the best way to get around but flying has its risks. Aviation safety requires more than just a pilot’s skill–it takes all of us. Learn more about aviation to increase the safety of your next park flight.

Alaska is one of the most heavily glaciated areas in the world outside of the polar regions. Approximately 23,000 square miles of the state are covered in glaciers—an area nearly the size of West Virginia. Glaciers have shaped much of Alaska’s landscape and continue to influence its lands, waters, and ecosystems. Because of their importance, National Park Service scientists measure glacier change. They found that glaciers are shrinking in area and volume across the state.

The rugged beauty of Alaska has been the homelands of Alaska Native people for thousands of generations. Today the relentless march of climate change threatens a range of cultural resources from archeological sites to historic cemeteries. Now the National Park Service is in a race to document heritage across the parklands in Alaska.

The landscape of Aniakchak is a vibrant reminder of Alaska's location in the volcanically active Ring of Fire. In spite of such violent volcanic events, the living world, animal and human, eventually adjusted, recovered, and endured. The history of Aniakchak Caldera exemplifies the destructive force of nature while also demonstrating the resiliency of people.

Achieving consistency in permitting decisions across multiple units of the National Park System remains a constant challenge. When opportunities allow, park managers combine environmental compliance for related projects spanning several units, such as the installation of climate monitoring stations for the Inventory & Monitoring networks.

This field guide to bumble bees will help you identify these abundant and conspicuous pollinators, which are found across most of Alaska. They are well-adapted to cold, harsh climates and live in every habitat where there are flowers offering up pollen and nectar, including forests, shrublands, tundra, wetlands, riparian areas, beaches, and gardens.

Calderas are large collapse features that can be many miles in diameter. They form during especially large eruptions when the magma chamber is partially emptied, and the ground above it collapses into the momentary void. Crater Lake and Aniakchak Crater are calderas.
