The Sargent Icefield is a large icefield located on the eastern portion of the Kenai Peninsula bordering Prince William Sound in Alaska. [1] The ice field has numerous outflow glaciers including the Chenega, Princeton, and Ellsworth Glaciers.
The Kenai Peninsula is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina, who historically inhabited the area. They called the Kenai Peninsula Yaghanen.
The Columbia Icefield is the largest ice field in North America's Rocky Mountains. Located within the Canadian Rocky Mountains astride the Continental Divide along the border of British Columbia and Alberta, Canada, the ice field lies partly in the northwestern tip of Banff National Park and partly in the southern end of Jasper National Park. It is about 325 square kilometres (125 sq mi) in area, 100 metres (330 ft) to 365 metres (1,198 ft) in depth and receives up to 7 metres (280 in) of snowfall per year.
The Kenai Mountains are a mountain range in the U.S. state of Alaska. They extend 192 km (120 mi) northeast from the southern end of the Kenai Peninsula to the Chugach Mountains, and have an average elevation of 3,000 to 5,000 feet.
An ice field is a mass of interconnected valley glaciers on a mountain mass with protruding rock ridges or summits. They are often found in the colder climates and higher altitudes of the world where there is sufficient precipitation for them to form. The higher peaks of the underlying mountain rock that protrude through the icefields are known as nunataks. Ice fields are larger than alpine glaciers, but smaller than ice caps and ice sheets. The topography of ice fields is determined by the shape of the surrounding landforms, while ice caps have their own forms overriding underlying shapes.
Chenega Glacier is a tidewater glacier located in Prince William Sound and on the Kenai Peninsula in the U.S. state of Alaska.
The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. The glacier currently loses depth at a rate of about 5 metres (16 ft) per year and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years. Easily accessible, it is the most visited glacier in North America. The leading edge of the glacier is within easy walking distance; however, travel onto the glacier is not recommended unless properly equipped. Hidden crevasses have led to the deaths of unprepared tourists.
The Peyto Glacier is situated in the Canadian Rockies in Banff National Park, Alberta, Canada, approximately 90 km (56 mi) northwest of the town of Banff, and can be accessed from the Icefields Parkway. Peyto Glacier is an outflow glacier from the Wapta Icefield, which rests along the Continental divide. The glacier snout is subject to high melt rates from season to season and there is marked surface lowering on several parts of the glacier. Glacial silt, which is carried from the glacier by streams, ensures a turquoise appearance to Peyto Lake, a popular touring destination. As is true for the vast majority of glaciers worldwide, Peyto Glacier has been retreating rapidly, especially since the last half of the 20th century, and has reportedly lost 70% of its mass since it was first researched (Demuth and Keller, 2006). Between 1896 and 1966, the total volume loss of the Peyto Glacier was 1088.5 x 106 m3 (Wallace, 1995). A 1896's photograph by Walter D. Wilcox was the first record of this glacier, although the significant research did not start until 1965. In 1987, an automatic weather station was constructed near the glacier that monitors temperature changes, radiation and precipitation.
Bow Glacier is located in Banff National Park, Alberta, Canada, approximately 37 km (23 mi) northwest of Lake Louise. It can be viewed from the Icefields Parkway. Bow Glacier is an outflow glacier from the Wapta Icefield, which rests along the Continental Divide, and runoff from the glacier supplies water to Bow Lake and the Bow River. The glacier is credited for creating the Bow Valley before retreating at the end of the last glacial maximum.
Vulture Glacier is located in Banff National Park, Alberta, Canada, northwest of Lake Louise, and can be viewed from the Icefields Parkway. Vulture Glacier is an outflow glacier from the Wapta Icefield, which rests along the Continental Divide. The glacier had an area of 4.9 square kilometres (1.9 sq mi) in the 1980s, however, all of the glaciers in the Canadian Rockies have been retreating steadily since the middle of the 19th century.
Crowfoot Glacier is located in Banff National Park, Alberta, Canada, 32 km (20 mi) northwest of Lake Louise, and can be viewed from the Icefields Parkway. The glacier is situated on the northeastern flank of Crowfoot Mountain.
The Waputik Icefield is located on the Continental divide in the Canadian Rocky Mountains, in the provinces of British Columbia and Alberta. It is developed on the heights of the Waputik Range in the Central Main Ranges.
The Wapta Icefield is located on the Continental Divide in the Waputik Mountains of the Canadian Rockies, in the provinces of British Columbia and Alberta. The icefield is shared by Banff and Yoho National Parks and numerous outlet glaciers extend from the icefield, including the Vulture, Bow and Peyto Glaciers. Runoff from the icefields and outlet glaciers supply water to both the Kicking Horse and Bow Rivers, as well as numerous streams and lakes.
The Saskatchewan Glacier is located in Banff National Park, Alberta, Canada, approximately 120 km (75 mi) northwest of the town of Banff, and can be accessed from the Icefields Parkway. Saskatchewan Glacier is the largest outflow glacier from the Columbia Icefield, which rests along the Continental Divide. The glacier is a primary water source for the North Saskatchewan River. The glacier is approximately 13 kilometres (8.1 mi) long and covers an area of 30 km2 (11.5 mi2) and was measured in 1960 to be over 400 metres (1,310 ft) thick at a distance of 8 kilometres (5.0 mi) from the terminal snout. Between the years 1893 and 1953, Saskatchewan Glacier had retreated a distance of 1,364 metres (4,475 ft), with the rate of retreat between the years 1948 and 1953 averaging 55 metres (180 ft) per year. The glacier, which flows northeast, exhibits a prominent medial morraine.
The Stikine Icecap is a large icefield straddled on the Alaska–British Columbia boundary in the Alaska Panhandle region. It lies in the Boundary Ranges of the Coast Mountains. Within the United States, most of it is under the administration of the Tongass National Forest and is part of the Stikine-LeConte Wilderness within the national forest.
The Princeton Glacier is a glacier in the Sargent Icefield, Kenai Peninsula in Alaska.
The Ha-Iltzuk Icefield is an icefield in the central Pacific Ranges of the Coast Mountains in British Columbia, Canada. It is the largest icefield in the Coast Mountains south of the Alaska Panhandle, with an area of 3,610 km2 (1,390 sq mi). It is located on the west side of the Klinaklini River and the Waddington Range. The highest summit in the icefield is Mount Silverthrone, which is a mountain on the northeast edge of a circular, 20 km (12 mi) wide, deeply dissected caldera complex called the Silverthrone Caldera.
The Lillooet Icecap, also called the Lillooet Icefield or the Lillooet Crown, is a large icefield in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is about 90 km (56 mi) northwest of the towns of Pemberton and Whistler, and about 175 km (109 mi) north of Vancouver, British Columbia. The Lillooet Icecap is one of the largest of several large icefields in the Pacific Ranges which are the largest temperate-latitude glacial fields in the world. At its maximum extent including its glacial tongues it measures 30 km (19 mi) east to west and 20 km (12 mi) north to south; its central icefield area is approximately 15 km (9 mi) in diameter.
Kluane / Wrangell–St. Elias / Glacier Bay / Tatshenshini-Alsek is an international park system located in Canada and the United States, at the border of Yukon, Alaska and British Columbia.
The Mamquam Icefield is an icefield in southwestern British Columbia, Canada, located at the headwaters of Skookum Creek. It lies at the southern end of Garibaldi Provincial Park and is one of the southernmost icefields in the Pacific Ranges of the Coast Mountains. The highest summit of the icefield is Mamquam Mountain, located at its southern end with an elevation of 2,588 m (8,491 ft).
Sinton is a crater in the Ismenius Lacus quadrangle on Mars. Sinton crater lies in the northern hemisphere, south of the very large crater Lyot and west of Ismeniae Fossae. It was named after Harvard astronomer William M. Sinton. The name was approved in 2007.
