Kaguyak caldera was formed following powerful dacitic explosive eruptions about 5800 years ago. An extensive apron of pyroclastic-flow deposits surrounds the 2.5-km-wide caldera. This view from the SW shows two post-caldera lava domes that form a peninsula into the lake and another lava dome that forms a small island that rises about 10 m above the center of the lake. The low notch at the far end of the caldera is a pre-caldera stream valley that was beheaded by caldera formation.

The small, but dramatic Kaguyak caldera on the northern Alaska Peninsula contains a lake more than 180-m deep whose surface is 550-m below the caldera rim. Two post-caldera lava domes form the large peak that rises above the rim of the 2.5-km-wide caldera at the right. The small island in the center of the lake is another lava dome. Collapse of the caldera occurred following powerful dacitic explosive eruptions about 5800 years ago. Shelikof Strait is visible at the top of the photo.

The small 2.5-km-wide Kaguyak caldera is filled by a lake that reaches 550 m below the caldera rim, seen here from the west. A lava dome extends into the lake on the SW side and another dome forms a small island in the center of the lake. The voluminous caldera-forming deposits have been radiocarbon dated at 5,800 years old. A large pre-caldera lava dome forms the high point on the eastern caldera rim. The broad valley of Big River descends to Shelikof Strait to the upper right.

Fourpeaked volcano to the upper left is one of a group of volcanoes NE of Katmai National Park, beyond the 2.5-km-wide Kaguyak caldera in the foreground. Much of the surface is hidden beneath Fourpeaked Glacier; the few exposed outcrops are lava flows interlayered with volcanic agglomerate. Deposits near the summit are extensively hydrothermally altered.

Snow and ice cover the Kaguyak caldera lake in this view from the NW. The caldera formed during a voluminous eruption about 5,800 years ago that produced pyroclastic flows that reached Shelikof Strait. Two lava domes, one large and the other seen just above the center of the lake, were built after the caldera-forming eruption.
