Edgecumbe
Edgecumbe Volcano near Sitka Alaska by Duncan Marriott, December 2004. Many people forget that young volcanoes also exist in southeast Alaska. This lovely photograph of Mount Edgecumbe located about 25 km west of Sitka on the other side of Sitka Sound illustrates that volcanic activity has also occurred in the not-too-distant geologic past in the Alaska panhandle.

Jarvis
Mount Jarvis, 4,091 m (13,421 ft) high, is the youngest volcano in the eastern Wrangell volcanic field. Mount Jarvis was active approximately 1 to 2 million years ago. View is to the southeast. Photograph by R. McGimsey, U.S. Geological Survey, July 15, 1991.

Cleveland
Mount Cleveland forms the western half of Chuginadak Island in the central Aleutian Islands. This symmetrical, 1,730-m (5,676 ft)-high stratovolcano and has been the site of numerous eruptions in the last two centuries; the most recent eruption occurred in 1994. In 1944, a U.S. Army serviceman was reportedly killed by an eruption from Mount Cleveland. Photograph by M. Harbin, University of Alaska Fairbanks, July 24, 1994.

Cleveland
False color composite satellite image of the second eruption of Mount Cleveland volcano in 2001. The volcano is located on the western half of Chuginadak Island in the east-central Aleutian Islands of Alaska. Chuginadak Island is part of the Island of Four Mountains. Mt. Cleveland erupted in 2001 on February 19, March 11, and March 19. The volcano has erupted 16 other times since 1893. Composite produced with a Red-Green-Blue channel combination of Band 7 - Band 5 - Band 4 respectively. This combination produces an image that brings out the hotter regions. The lava flow on the western flank of the volcano is hottest when the color is yellow. The reddish glow is an artifact. The ash plume from this eruption can be seen extending to the northeast and is cooler where the grayish-purple color is. Produced by Steve J. Smith, Volcanology/Remote Sensing Graduate Student from the Geophysical Institute University of Alaska Fairbanks, the College of Science, Engineering, and Mathematics, and the Alaska Volcano Observatory. Image was run through a linear 2% enhancement.

Kaguyak

Tana
Looking eastward across the isthmus of Chuginadak, a cinder cone of probable Holocene age is at the right with Tana volcano in the background. The southwest flank of Tana peak has a large shallow explosion crater and large ballistic blocks litter the slope below this crater.

Amchixtam Chaxsxii
This image of submarine topography shows a previously unknown volcano mapped by Jennifer Reynolds (UAF School of Fisheries and Ocean Sciences), during an oceanographic cruise in 2003 funded by the North Pacific Research Board. The purpose of the cruise was to create seafloor maps for studies of deep-water coral habitat. The 1900-ft tall volcano has been named Amchixtam Chaxsxii (Am'chik-tam Chakh-skiee), a name in the Atka dialect of the Unangan language suggested by the local Aleut community. The discovery of a previously unknown volcano in the Aleutian arc illustrates the extent to which basic exploration in the Aleutian is needed.

Recheshnoi
View, looking west, at the head of the Russian Bay valley of Mount Recheshnoi, a deeply dissected, 1,984-m (6,510 ft)-high stratovolcano on central Umnak Island in the eastern Aleutian Islands. Unlike Vsevidof volcano, its neighbor to the west, Recheshnoi volcano has had no documented historical eruptions. Photograph by C. Nye, Alaska Division of Geological and Geophysical Surveys, August, 1985.

Veniaminof
Strombolian burst of incandescent lava fragments from the intracaldera cinder cone at Veniaminof volcano on the Alaska Peninsula. Veniaminof volcano is a 2,507-m (8,225 ft)-high stratovolcano with a summit caldera that formed about 3,700 years ago. The caldera is now ice-filled. View is to the northwest. Photograph by M.E. Yount, U.S. Geological Survey, July 13, 1983.
