Griggs volcano, 2265-m-high, is the highest of a group of volcanoes in the Katmai area. It lies 10 km behind the volcanic arc defined by other Katmai group volcanoes. Griggs is only slightly dissected and is largely of Holocene age. Although no historical eruptions have been reported from Griggs, vigorously active fumarolic fields persist in a summit crater and along the upper SW flank. The slopes of Griggs are heavily mantled by fallout from the 1912 Novarupta eruption in this 1990 view from the SW.

Mount Griggs, seen here from the west rim of Katmai caldera, is a 2265-m stratovolcano that lies west of a NE-trending arc of volcanoes cutting across Katmai National Park. No historical eruptions are known from this largely Holocene volcano. Noisy fumarolic jets at the summit of Griggs can be heard from long distances.

Geologists walk toward 2265-m-high Griggs volcano from the base of Knife Creek Glacier to its south. The relatively unmodified slopes of the volcano reflect its largely Holocene age. Although no historical eruptions have been reported from Griggs, vigorously active fumarolic fields persist in a summit crater and along the upper SW flank. Noisy fumarole jets can be heard from the valley floor. The slopes of Griggs and the surface of Knife Creek Glacier are heavily mantled by gray fallout from the 1912 Novarupta eruption.
