Mount Griggs

Mount Griggs is a stratovolcano in Katmai National Park on the Alaska Peninsula, part of the Aleutian volcanic arc. It forms one element of the park’s volcanic landscape and is largely remote and glacier- or snow-covered at higher elevations.

The area around the volcano is dominated by volcanic deposits and rugged terrain; the mountain is most often visited indirectly via flightseeing tours or by researchers and experienced backcountry parties operating from park airstrips. Views of the volcano are commonly obtained from aircraft and park boat or floatplane operations.

The peak belongs to the Katmai volcanic region, which includes a number of large calderas and vents; the broader area is notable for 20th-century geological study and for the major 1912 Novarupta event that shaped much of the park’s landscape.

The volcano lies within the Katmai National Park region of the Alaska Peninsula; the nearest logistics hubs for access are park airstrips and communities that operate charter flights into the park.

• Park and arc: Located within Katmai National Park and Preserve on the Alaska Peninsula and forming part of the Aleutian volcanic arc.
• Access: Remote and largely accessible only by air or extended overland travel; commonly seen on flightseeing routes in the Katmai region.
