A National Park Service report on Alaska's glaciers noted glaciers within Alaska national parks shrank 8% between the 1950s and early 2000s and glacier-covered area across the state decreased by ...
Matanuska Glacier is a valley glacier in the US state of Alaska. At 27 miles (43 km) long by 4 miles (6.4 km) wide, it is the largest glacier accessible by car in the United States. Its terminus feeds the Matanuska River. [2] It lies near the Glenn Highway about 100 miles (160 km) northeast of Anchorage in Glacier View. The glacier flows about ...
View of the Juneau Icefield. The Juneau Icefield is an ice field located just north of Juneau, Alaska, continuing north through the border with British Columbia, [1] extending through an area of 3,900 square kilometres (1,500 sq mi) in the Coast Range ranging 140 km (87 mi) north to south and 75 km (47 mi) east to west.
The bursting of such snow-and-ice dams is a phenomenon called a jökuhlaup, and while it’s relatively little-known in the U.S., researchers say such glacial floods could threaten about 15 ...

The melting of Alaska's Juneau icefield, home to more than 1,000 glaciers, is accelerating. The snow covered area is now shrinking 4.6 times faster than it was in the 1980s, according to a new study.
Hayes Volcano is an ice-shrouded, glacially scoured eruptive center of Quaternary age composed of pyroclastic deposits, volcanic breccia, and lava domes.Although the edifice of the volcano is largely covered by glacier ice, parts of small lava domes, dome debris, and pyroclastic deposits project through the ice at altitudes of 2,400 to 2,800 meters above sea level.
They can be up to 10 meters wide and are typically found on ice sheets and flat areas of a glacier in a region of transverse crevasses. Moulins can reach the bottom of the glacier, hundreds of meters deep, [ 3 ] [ 4 ] [ 5 ] or may only reach the depth of common crevasse formation (about 10–40 m) where the stream flows englacially.
