Mount Mageik, Stratovolcano in Katmai National Park, Alaska

Mount Mageik is a stratovolcano in Katmai National Park in Alaska, rising to about 7,100 feet in elevation. The volcano has multiple summit peaks covered by glacial ice, and its crater contains a lake.

Mount Mageik has no confirmed historical eruptions; its youngest eruptive products are Holocene, dated to between 8750 and 500 BCE, and a 1946 eruption report is now considered questionable. The volcano is mantled in ash from the 1912 eruption of Novarupta and from the 1953 eruption of nearby Trident Volcano.

The name Mageik comes from the volcano's designation on early maps of the Alaska Peninsula, and the mountain is listed among the volcanoes of the Aleutian Range. Its slopes lie within Katmai National Park and Preserve, managed by the U.S. National Park Service.

The volcano is monitored by the Alaska Volcano Observatory for seismic activity and volcanic hazards. Visitors should check current conditions before traveling to ensure safe access to the area.

The northeast flank features intense fumarolic activity with visible sulfur deposits forming on the rocks. This geothermal venting shows the ongoing heat beneath the mountain's surface.
