Johns Hopkins Glacier (Lingít: Tsalxaan Niyaadé Sít’) is a 12-mile (19 km) long glacier located in Glacier Bay National Park and Preserve in the U.S. state of Alaska.It begins on the east slopes of Lituya Mountain and Mount Salisbury, and trends east to the head of Johns Hopkins Inlet, 1 mile (1.6 km) southwest of the terminus of Clark Glacier on Mount Abbe, and 79 miles (127 km ...
Mount Abbe is an 8200+ feet (2499+ meter) double summit mountain located in the Fairweather Range of the Saint Elias Mountains, in southeast Alaska. [3] The peak is situated near the terminus of the Johns Hopkins Glacier, within Glacier Bay National Park and Preserve, 100 mi (161 km) northwest of Juneau, and 8.2 mi (13 km) northeast of Mount Orville.
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. [1] It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an ...
Precipitation runoff from the mountain drains to Johns Hopkins Inlet where cruise ships allow views of the peak and the Johns Hopkins Glacier.Although modest in elevation, topographic relief is significant as the summit rises up from tidewater in seven miles (11 km) and the north face rises 6,100 feet (1,860 m) in 1.5 mi (2.4 km).
This climate supports hanging glaciers on its slopes as well as the immense Brady Glacier to the south, Reid Glacier to the northeast, and Johns Hopkins Glacier to the northwest. Precipitation runoff and meltwater from its glaciers drains into Glacier Bay and the Gulf of Alaska.
Glacier Bay National Park and Preserve is an national park of the United States located in Southeast Alaska west of Juneau. President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 26, 1925. [4] Subsequent to an expansion of the monument by President Jimmy Carter in 1978, the ...
The Extreme Ice Survey (EIS), based in Boulder, Colorado, uses time-lapse photography, conventional photography and video to document the effects of global warming on glacial ice. It is the most wide-ranging glacier study ever conducted using ground-based, real-time photography. Starting in 2007 the EIS team installed as many as 43 time-lapse ...
The glacier retreated 1.9 kilometres (1.2 mi) in 33 years. The retreat of glaciers since 1850 is a well-documented effect of climate change. The retreat of mountain glaciers provide evidence for the rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, the Alps in central ...
