Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Fisher
This 1974 view shows part of the interior of Fisher caldera on Unimak Island in the eastern Aleutian Islands. Fisher is an 11 x 18 km caldera that formed about 9,100 years ago during the eruption of pyroclastic flows that overtopped topographic barriers more than 500 m high. The caldera contains several lakes, maars, and other vents. Photo by Tom Miller, 1974 (Alaska Volcano Observatory, U.S. Geological Survey).

The Fisher caldera, on western Unimak Island NE of Westdahl volcano, is 11 x 18 km elongated in a NE direction It formed around 9,400 years ago, accompanied by emission of large-volume pyroclastic flows that reached the Bering Sea and the Pacific Ocean. Two cones are located below the N rim, NE of its high point at Eickelberg Peak, which rises more than 900 m above three lakes on the caldera floor, one of which drains through a notch in the southern caldera rim. A large composite cone, Mount Finch, is found at the center of the caldera, which also contains a small breached cinder cone. Eruptions have occurred in the 18th and 19th centuries. Low-temperature fumaroles are located on the W flank of Mount Finch, and Turquoise Lake, at the base of the cone, emits hydrogen sulfide gas.
