Mount Baker, also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active glacier-covered andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington State in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount St. Helens. About 30 miles (48 km) due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current volcanic cone is likely no more than 140,000 years old, and possibly no older than 80–90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
Mount Erebus is the southernmost active volcano on Earth, located on Ross Island in the Ross Dependency in Antarctica. With a summit elevation of 3,792 metres (12,441 ft), it is the second most prominent mountain in Antarctica and the second-highest volcano in Antarctica. It is the highest point on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova. It makes Ross Island the sixth-highest island on Earth.
Mount Rainier National Park is a national park of the United States located in southeast Pierce County and northeast Lewis County in Washington state. The park was established on March 2, 1899, as the fourth national park in the United States, preserving 236,381 acres including all of Mount Rainier, a 14,410-foot (4,390 m) stratovolcano. The mountain rises abruptly from the surrounding land with elevations in the park ranging from 1,600 feet to over 14,000 feet (490–4,300 m). The highest point in the Cascade Range, Mount Rainier is surrounded by valleys, waterfalls, subalpine meadows, and 91,000 acres of old-growth forest. More than 25 glaciers descend the flanks of the volcano, which is often shrouded in clouds that dump enormous amounts of rain and snow.
Mount Adams, known by some Native American tribes as Pahto or Klickitat, is an active stratovolcano in the Cascade Range. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. It is the second-highest mountain in Washington, after Mount Rainier.
Gifford Pinchot National Forest is a National Forest located in southern Washington, managed by the United States Forest Service. With an area of 1.32 million acres (5,300 km2), it extends 116 km (72 mi) along the western slopes of Cascade Range from Mount Rainier National Park to the Columbia River. The forest straddles the crest of the South Cascades of Washington State, spread out over broad old-growth forests, high mountain meadows, several glaciers, and numerous volcanic peaks. The forest's highest point is at 12,276 ft (3,742 m) at the top of Mount Adams, the second-tallest volcano in the state after Rainier. Often found abbreviated GPNF on maps and in texts, it includes the 110,000-acre (450 km2) Mount St. Helens National Volcanic Monument, established by Congress in 1982.
Glacier National Park is part of a system of 43 parks and park reserves across Canada, and one of seven national parks in British Columbia. Established in 1886, the park encompasses 1,349 km2 (521 sq mi), and includes a portion of the Selkirk Mountains, which are part of the larger grouping of mountains, the Columbia Mountains. It also contains the Rogers Pass National Historic Site.
A glacier cave is a cave formed within the ice of a glacier. Glacier caves are often called ice caves, but the latter term is properly used to describe bedrock caves that contain year-round ice.
The Nisqually Glacier is one of the larger glaciers on the southwestern face of Mount Rainier in the U.S. state of Washington. The glacier is one of the most easily viewed on the mountain, and is accessible from the Paradise visitor facilities in Mount Rainier National Park. Nisqually Glacier is the source of the Nisqually River.
The Crater Glacier is a geologically young glacier on Mount St. Helens, in the U.S. state of Washington. The glacier formed after the 1980 eruption and due to its location, the body of ice grew rapidly, unknown to the public for nearly 20 years. The glacier once contained ice caves in the smooth ice before the 2004–2008 volcanic activity. The growth of the lava dome and volcanic eruptions from 2004 to 2008 significantly altered the appearance of the glacier. In the same time period, several agencies decided to put an official name on the glacier which, at first, was Tulutson Glacier. A later decision made Crater Glacier the official glacier name. Despite the volcanic activity, the glacier continued to advance and by mid-2008, the glacier completely encircled the lava domes. In addition, new glaciers have formed around Crater Glacier as well.
The Erebus Glacier Tongue is a mountain outlet glacier and the seaward extension of Erebus Glacier from Ross Island. It projects 11 kilometres (6.8 mi) into McMurdo Sound from the Ross Island coastline near Cape Evans, Antarctica. The glacier tongue varies in thickness from 50 metres (160 ft) at the snout to 300 metres (980 ft) at the point where it is grounded on the shoreline. Explorers from Robert F. Scott's Discovery Expedition (1901–1904) named and charted the glacier tongue.
The Williwakas Glacier was a glacier located on the south flank of Mount Rainier in Washington. The glacier lies below the Paradise Glacier. Due to its relatively low elevation—6,600 feet (2,000 m)–6,900 feet (2,100 m)—the glacier is small and surrounded by small snow fields above the regional tree line. A stubby 7,163 ft (2,183 m) peak is located to the east of the glacier.
The Cowlitz Glacier is on the southeast flank of Mount Rainier in the U.S. state of Washington. The body of ice covers 1.3 square miles (3.4 km2) and has a volume of 6 billion ft3. The glacier starts at an elevation of 10,700 feet (3,300 m) and flows southeast. An adjacent glacier, the Paradise Glacier, is connected to this glacier on its southwest margin. As it flows down the slopes of Mount Rainier it nearly meets up with the Ingraham Glacier and during the Little Ice Age, which ended around the year 1850, the two glaciers shared a common terminus. Meltwater from the glacier drains into the Cowlitz River.
Flett Glacier refers to two glaciers on the northwestern flank of Mount Rainier in the U.S. state of Washington. The glaciers lie on a subsidiary peak of Rainier, the 8,364 feet (2,549 m) Observation Rock. There are two sections of glacial ice, an eastern lobe at about 7,600 ft (2,300 m) to 7,300 ft (2,200 m) in elevation, a smaller western lobe at about 7,200 ft (2,200 m) in elevation. Meltwater from the glacier flows into the Puyallup River.
Ingraham Glacier is on the south-eastern flank of Mount Rainier, in the U.S. state of Washington. The glacier is named for the Mount Rainier enthusiast Edward Sturgis Ingraham. From the summit ice cap, Ingraham Glacier flows east between Gibraltar Rock,, and Disappointment Cleaver and south of Little Tahoma Peak, which divides it from the much larger Emmons Glacier to the north. Descending southeast, it approaches the east flank of Cowlitz Glacier and the two glaciers nearly join at 6,700 ft (2,000 m). Meltwater from the glacier drains into the Cowlitz River.
Paradise Glacier is a glacier on the southeast flank of Mount Rainier in Washington. It covers 0.4 square miles (1.0 km2) and contains 0.8 billion ft3 with Stevens Glacier included. The glacier is bounded to the west by the Muir Snowfield, Anvil Rock and McClure Rock. There is a single extant main lobe of the glacier, ranging from 9,000 feet (2,700 m) to 7,200 feet (2,200 m), that is connected to the larger Cowlitz Glacier. To the south, there was a smaller portion which was near the Cowlitz Rocks and the tiny Williwakas Glacier, ranging from 6,900 feet (2,100 m) to 6,400 ft (2,000 m) in elevation and containing the Paradise Ice Caves until the 1990s. This smaller lobe melted between 2004 and 2006. Meltwater from the glacier drains into the Cowlitz River.
Paradise is the name of an area at approximately 5,400 feet (1,600 m) on the south slope of Mount Rainier in Mount Rainier National Park in Washington, United States. Southeast of Seattle, the area lies on the border of Pierce and Lewis counties and includes the Paradise Valley and the Paradise Glacier, the source of the Paradise River. Virinda Longmire named Paradise in the summer of 1885 while she viewed the wildflowers in the alpine meadows there. Paradise also offers views of Mount Rainier and the Tatoosh Range.
Shambles Glacier is a steep glacier 4 miles (6 km) long and 6 miles (10 km) wide, with very prominent hummocks and crevasses, flowing east between Mount Bouvier and Mount Mangin into Stonehouse Bay on the east side of Adelaide Island. It is the island's largest glacier, and provides an eastern outlet from the giant Fuchs Ice Piedmont which covers the entire western two-thirds of the island. In doing so, Shambles Glacier provides the largest 'gap' in Adelaide Island's north–south running mountain chain.
Camp Muir, named for the naturalist John Muir, is a high-altitude refuge for climbers in Mount Rainier National Park in Washington, accessed through the Paradise Entrance. The shelters comprising the camp are situated at a 10,188 ft (3,105 m) elevation between the Muir Snowfield and the Cowlitz Glacier on Mount Rainier. Camp Muir is the most-used high camp for those attempting to climb to the mountain's summit. Camp Muir is between the Nisqually and Paradise Glaciers.
Mount Rainier, also known as Tahoma, is a large active stratovolcano in the Cascade Range of the Pacific Northwest in the United States. The mountain is located in Mount Rainier National Park about 59 miles (95 km) south-southeast of Seattle. With an officially recognized summit elevation of 14,410 ft (4,392 m) at the Columbia Crest, it is the highest mountain in the U.S. state of Washington, the most topographically prominent mountain in the contiguous United States, and the tallest in the Cascade Volcanic Arc.
