PIX4672391 Glacier Malaspina, Alaska, Landsat - 7 - Malaspina Glacier, Alaska, observed by satellite Landsat - 7 on 31/08/2000

PIX4672451 Malaspina Glacier, Alaska. 08/1989 - Malaspina Glacier, Alaska, U.S.A. August 1989 - Malaspina Glacier, Alaska, observes from Space Shuttle Columbia. Malaspina Glacier can be seen just left of the center of this northeast - looking, low - oblique photograph. Located in southern Alaska on the shore of the Gulf of Alaska, Malaspina Glacier is a classic example of a piedmont glacier lying at the foot of a mountain range - - in this case, the Saint Elias Mountains (just north of the glacier). The glacier covers an area of 1500 square miles (3900 square kilometers) on the coastal plain, is almost 60 miles (97 kilometers) long, and is more than 1000 feet (300 meters) thick. The Seward Ice Field is the main source of ice for the glacier. The glacier moves in surges that push earlier - formed moraines outward into expanding concentric patterns, which you can see along the flanks of the ice mass. To the northwest of Malaspina Glacier is the curved and pointed Agassiz Glacier, which is also fed by the Seward Ice Field. To the northeast of Malaspina Glacier, located at the head of Yakutat Bay, is the Hubbard Glacier, which surged in 1989, blocking the entrance to Russell Fiord and temporarily trapping a large number of marine animals

PIX4672430 Glacier Malaspina, Alaska - The Malaspina Glacier in Alaska - Le Glacier Malaspina, Alaska, from perspective. This image is the result of joint observations made by the Landsat-7 satellite in August 2000 in visible and infrared, combined with elevation radar data obtained by the SRTM (Shuttle Radar Topography Mission) in February 2000. This glacier extends over 3000 km2. Natural colours have been applied to this image: light blue, ice, white, snow, green vegetation, grey rock and blue for the ocean. Malaspina Glacier in southeastern Alaska is considered the classic example of a piedmont glacier. Piedmont glaciers occur where valley glaciers exit a mountain range onto broad lowlands, are no longer laterally confined, and spread to become wide lobes. Malaspina Glacier is actually a compound glacier, formed by the merger of several valley glaciers, the most prominent of which seen here are Agassiz Glacier (left) and Seward Glacier (right). In total, Malaspina Glacier is up to 65 kilometers (40 miles) wide and extends up to 45 kilometers (28 miles) from the mountain front nearly to the sea. This perspective view was created from a Landsat satellite image and an elevation model generated by the Shuttle Radar Topography Mission (SRTM). Landsat views both visible and infrared light, which have been combined here into a color composite that generally shows glacial ice in light blue, snow in white, vegetation in green, bare rock in grays and tans, and the ocean (foreground) in dark blue. The back (northern) edge of the data set forms a false horizon that meets a false sky. Glaciers are sensitive indicators of climatic change

PIX4672485 Hubbard Glacier - Alaska - Hubbard Glacier - Alaska - The Hubbard Glacier is the longest glacier in North America to the sea. Hubbard Glacier, the largest tidewater glacier in the world. The Hubbard and Turner/Haenke Glaciers extend out into Disenchantment Bay (discovered and named by Captain Alejandro Malaspina in 1791, who was disappointed to find the inlet was a dead end). The face of Hubbard Glacier extends 6 1/2 miles in length. The towering ice peaks making up the face of the glacier are 400 to 500 feet high! To give some perspective the Wrangell - St. Elias mountain peaks in the background are all between 14,000 and 18,000 feet in elevation, the tallest coastal mountains in the world
