Caption:Mount Wrangell, a 4,317-m (14,163 ft)-high andesite shield volcano is visible to the left on the skyline; it is the only volcano in the Wrangell Mountains to have had documented historical activity. This consisted of several minor, possibly phreatic eruptions in the early 1900's. Mount Drum, 3,661 m (12,011 ft) high, is the westernmost volcano in the Wrangell volcanic field, and is visible to the right on the skyline. The Copper River is in the foreground. View is to the southeast. Photograph by D. Richter, U.S. Geological Survey, August 1981.

Caption:Landsat 7 ETM+ satellite image (Path 78, Row 23) of the Island of Four Mountains in the Central Aleutian Islands of Alaska. This image is a false color composite image produced by setting Landsat 7 bands 5-4-2 equal to the red-green-blue channels respectively. This image displays some of the volcanic deposits on the western and southeastern flanks of Mt. Cleveland from the Feb-Mar 2001 eruptions. The main 2001 lava flow is on the western flank, where a volcaniclastic debris flow was deposited earlier in the February 2001 eruption. Lahar deposits also extended down the south and southeast flanks. Most of the 2001 ashfall was on the eastern half of the edifice.

Caption:Landsat 7 ETM+ satellite image (Path 78, Row 23) of the Island of Four Mountains in the Central Aleutian Islands of Alaska. This is a thermal band image where the lighter shades indicate higher thermal energy being received by the satellite. The brighter linear feature on the western side of Mt. Cleveland is the main 2001 lava flow from the eruption.

Caption:Landsat 7 ETM+ satellite image (Path 79, Row 23) of the March 11, 2001 Eruption of Mt. Cleveland in the Central Aleutian Islands of Alaska. 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. The image was run through a linear 2% enhancement and a 3x3 high pass filter to sharpen it.

This is a thermal band image where the lighter shades indicate higher thermal energy being received by the satellite. The brighter linear feature on the western side of Mt. Cleveland is the main 2001 lava flow from the eruption. The eruption plume extends to the northeast, and is actually colder than the surrounding area making the plume appear really dark.
