EdgecumbeEdgecumbe 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.

JarvisMount 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.

ClevelandMount 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.
ClevelandFalse 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.
KaguyakThe 2.5-km (1.5 mi)-diameter, lake-filled caldera of Kaguyak volcano truncates a former
stratovolcano. Postcaldera lava domes form a prominent peninsula (right center) and a small island. Photograph by C. Nye, Alaska Division of Geological and Geophysical Surveys, August, 1982.

Amchixtam ChaxsxiiThis 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.
RecheshnoiView, 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.

VeniaminofStrombolian 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.
