Mount Shuksan is a glaciated massif in the North Cascades National Park. Shuksan rises in Whatcom County, Washington immediately to the east of Mount Baker, and 11.6 miles (18.7 km) south of the Canada–US border. The mountain's name Shuksan is derived from the Lummi word [šéqsən], said to mean "high peak". The highest point on the mountain is a three sided peak known as Summit Pyramid.
The Usarp Mountains is a major Antarctic mountain range, lying westward of the Rennick Glacier and trending N-S for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills. Its important constituent parts include Welcome Mountain, Mount Van der Hoeven, Mount Weihaupt, Mount Stuart, Mount Lorius, Smith Bench, Mount Roberts, Pomerantz Tableland, Daniels Range, Emlen Peaks, Helliwell Hills and Morozumi Range.
Blackfoot Glacier is the second largest of the remaining 25 glaciers in Glacier National Park, Montana. Blackfoot Glacier is just to the north of Blackfoot Mountain and near Jackson Glacier. The glacier was most recently measured in 2005 at 441 acres (1.78 km2), yet when first documented in 1850, the glacier also included the now separate Jackson Glacier and together, they covered 1,875 acres (7.59 km2). In 1850, there were an estimated 150 glaciers in the park. Glaciologists have stated that by the year 2030, all the glaciers in the park may disappear. However, under a modest increase in overall carbon dioxide levels, some glaciers will remain until the late 23rd century.
Jackson Glacier is approximately the seventh largest of the remaining 25 glaciers in Glacier National Park located in the US state of Montana. A part of the largest grouping of glaciers in the park, Jackson Glacier rests on the north side of Mount Jackson. The glacier was most recently measured in 2005 at 250 acres (1.0 km2), yet when first documented in 1850, the glacier also included the now separate Blackfoot Glacier and together, they covered 1,875 acres (7.59 km2). Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage. When the two mountains were united prior to their separation sometime before 1929, they were known simply as Blackfoot Glacier.
Lower Curtis Glacier is in North Cascades National Park in the U.S. state of Washington. Named for photographer Asahel Curtis, the glacier is in a cirque on the western slopes of Mount Shuksan. Lower Curtis Glacier is rapidly retreating and has a negative mass balance, meaning that the rate of snow and ice that is falling in the accumulation zone is less than that which is lost each year in the ablation zone. Between 1908 and 1984, the glacier experienced a loss of thickness by 45 meters (147 ft). Between 1984 and 2002, the glacier lost another 6 meters (19 ft) in thickness. Lower Curtis Glacier also lost 28% of its surface area between the end of the little ice age and 1950. Between the years 1951 and 1979, the glacier actually lengthened by 245 meters (800 ft) but has retreated 184 m (600 ft) since 1985, partly due to the tongue of the glacier being on a steep precipice which may have increased the loss of ice at the termini.
Anthony Glacier is a glacier which flows in an east-southeast direction to the east coast of Palmer Land where it terminates opposite the south tip of Hearst Island. The upper part of this glacier was seen by a sledge party of the British Graham Land Expedition under John Riddoch Rymill in 1936–37. The glacier was seen from the seaward side in 1940 by a sledging party from the East Base of the United States Antarctic Service, and in 1947 was photographed from the air by the Ronne Antarctic Research Expedition (RARE). It was named by Finn Ronne for Alexander Anthony of the J.P. Stevens Company, New York City, which contributed windproof clothing to the RARE.
Finley Glacier is a tributary glacier which drains the northwest slopes of Mount Monteagle and flows north into the upper part of Icebreaker Glacier, in the Mountaineer Range, Victoria Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for Russell H. Finley, an aviation boatswain's mate with Squadron VX-6 during U.S. Navy Operation Deep Freeze, 1966, 1967 and 1968.
Crystal Glacier is in North Cascades National Park in the U.S. state of Washington, on the south slopes of Mount Shuksan. Descending 1.25 mi (2.01 km) from just east of the summit of Mount Shuksan, near its origination point, Crystal Glacier is connected to the larger Sulphide Glacier to the west. Crystal Glacier descends from 8,200 to 5,800 ft, and is also connected to East Nooksack Glacier as well as Hanging Glacier near it uppermost margins. Both Crystal and Sulphide Glaciers have a series of 300-to-1,000-foot high cascades which are collectively referred to as Sulphide Basin Falls. Below these cascades lies Sulphide Lake, which empties over Sulphide Creek Falls, one of the highest waterfalls in North America with a nearly 2,200 ft (670 m) drop.
Sulphide Glacier is in North Cascades National Park in the U.S. state of Washington, on the south slopes of Mount Shuksan. Descending 1.85 mi (2.98 km) from the summit tower of Mount Shuksan, it is connected to Crystal Glacier to the east. Sulphide Glacier descends from 8,600 to 5,600 ft. Sulphide Glacier is along the route taken when Mount Shuksan was first climbed in 1906. Both Sulphide and Crystal Glaciers have a series of 300-to-1,000-foot high cascades which are collectively referred to as Sulphide Basin Falls. Below these cascades lies Sulphide Lake, which empties over Sulphide Creek Falls, one of the highest waterfalls in North America with a nearly 2,200 ft (670 m) drop.
East Nooksack Glacier is in North Cascades National Park in the U.S. state of Washington, on the eastern slopes of Mount Shuksan. East Nooksack Glacier is only .70 mi (1.13 km), but fills the upper portions of the Nooksack Cirque, spanning more than 2 mi (3.2 km). East Nooksack Glacier is connected to Crystal Glacier at its uppermost section at 7,800 ft (2,400 m). East Nooksack Glacier extends from Nooksack Tower to the northwest to Seahpo Peak to the southeast and meltwater from the glacier flows into the Nooksack River.
Hanging Glacier is in North Cascades National Park in the U.S. state of Washington, on the north slopes of Mount Shuksan. Hanging Glacier is connected to Crystal Glacier at its uppermost margin, and also flows into Upper Curtis Glacier. Hanging Glacier is along the route taken in the first technical ascent of Mount Shuksan in 1939.
Price Glacier is in North Cascades National Park in the U.S. state of Washington, on the northeast slopes of Mount Shuksan, below the subpeak known as Nooksack Tower. Price Glacier descends from 8,600 to 4,200 ft and is the steepest and most heavily crevasseed glacier on Mount Shuksan. The disconnected lowest portions of Price Glacier calve small icebergs into Price Lake.
White Salmon Glacier is in North Cascades National Park in the U.S. state of Washington, on the west slopes of Mount Shuksan. White Salmon Glacier is a series of small glaciers that descend to the north from a ridge feature known as Shuksan Arm. A climbers route follows the White Salmon Glacier to Fisher Chimney which provides a faster approach than others to the summit of Mount Shuksan.
West Nooksack Glacier is in North Cascades National Park in the U.S. state of Washington, on the eastern slopes of Mount Shuksan, immediately northeast of the subpeak called Nooksack Tower. West Nooksack Glacier is only .10 mi (0.16 km) in length and is a glacial remnant. West Nooksack Glacier provides meltwater for the Nooksack River.
Nooksack Cirque is in North Cascades National Park in the U.S. state of Washington, on the eastern slopes of Mount Shuksan. Nooksack Cirque was formed by glaciers and the East Nooksack Glacier is located in the cirque below the headwall known as Jagged Ridge. The cirque extends from a subpeak of Mount Shuksan called Nooksack Tower to Seahpo Peak, a distance of over 2 mi (3.2 km) in width. Nooksack Cirque streams and meltwater from the East Nooksack Glacier form the headwaters for the Nooksack River.
Nooksack Tower is in North Cascades National Park in the U.S. state of Washington. Nooksack Tower is part of the Mount Shuksan Massif and is .75 mi (1.21 km) northeast of the main summit of Shuksan. Nooksack Tower looms to the west over Nooksack Cirque. The East Nooksack Glacier lies to the southeast, West Nooksack Glacier to the east and Price Glacier is on the north flanks of the tower. Nooksack Tower is one of the most difficult mountains to climb in the Cascade Range, with loose rock, 50-degree or greater slopes and ice ridges as well as accessibility issues and exposure, all weighing into the climbing equation. The descent may require ten or more rappels.
Table Mountain Glacier is in Snoqualmie National Forest in the U.S. state of Washington, to the east of Table Mountain. This small glacier is less than .50 mi (0.80 km) west of Artist Point and situated on the north slope of Table Mountain.
Price Lake is located in North Cascades National Park, in the U. S. state of Washington. Price Lake was formed by the retreat of Price Glacier, which descends from the north slopes of Mount Shuksan. Price Glacier is broken into an upper and lower section and the lower section sometimes calves small icebergs into Price Lake.
Sulphide Lake is located in North Cascades National Park, in the U. S. state of Washington. Sulphide Lake lies in a cirque on the southeast slopes of Mount Shuksan. Several major cascades drop as much as 1,000 ft (300 m) into Sulphide Lake including Sulphide Basin Falls which is from melt off the Sulphide Glacier. After Sulphide Creek drains from Sulphide lake, it then plunges at least 2,000 ft (610 m) over a series of cascades called Sulphide Creek Falls, which is one of the tallest waterfalls in the U.S.
