Thornton Lakes are located in North Cascades National Park, in the U. S. state of Washington. 1 to 1.75 mi (1.61 to 2.82 km) southeast of Mount Triumph. Thornton Lakes can be accessed on foot from a trailhead in Ross Lake National Recreation Area. The hike of 5.2 mi (8.4 km) includes a 2,400-foot (730 m) altitude gain and a 500-foot (150 m) descent to Lower Thornton Lake. Two other lakes lie above the first one, unofficially named Middle and Upper Thornton Lakes. A designated backcountry camping zone is located at Lower Thornton Lake.These paternoster lakes consist of three lakes located
North Cascades National Park is an American national park in the state of Washington. At more than 500,000 acres (200,000 ha), North Cascades National Park is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park.
Grand Teton National Park is an American national park in northwestern Wyoming. At approximately 310,000 acres, the park includes the major peaks of the 40-mile-long (64 km) Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only 10 miles (16 km) south of Yellowstone National Park, to which it is connected by the National Park Service-managed John D. Rockefeller, Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost 18,000,000-acre (7,300,000 ha) Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems.
Crater Lake is a crater lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep caldera that was formed around 7,700 years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth.
Crater Lake National Park is an American national park located in southern Oregon. Established in 1902, Crater Lake is the fifth-oldest national park in the United States and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of a destroyed volcano, Mount Mazama, and the surrounding hills and forests.
Mount Rainier National Park is an American national park located in southeast Pierce County and northeast Lewis County in Washington state. The park was established on March 2, 1899 as the fifth national park in the United States, preserving 236,381 acres including all of Mount Rainier, a 14,411-foot (4,392 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.
Novarupta is a volcano that was formed in 1912, located on the Alaska Peninsula in Katmai National Park and Preserve, about 290 miles (470 km) southwest of Anchorage. Formed during the largest volcanic eruption of the 20th century, Novarupta released 30 times the volume of magma of the 1980 eruption of Mount St. Helens.
Banff is a town within Banff National Park in Alberta, Canada. It is located in Alberta's Rockies along the Trans-Canada Highway, approximately 126 km (78 mi) west of Calgary and 58 km (36 mi) east of Lake Louise.

Katmai National Park and Preserve is an American national park and preserve in southern Alaska, notable for the Valley of Ten Thousand Smokes and for its brown bears. The park and preserve encompass 4,093,077 acres, which is between the sizes of Connecticut and New Jersey. Most of the national park is a designated wilderness area where all hunting is banned. The park is named after Mount Katmai, its centerpiece stratovolcano. The park is located on the Alaska Peninsula, across from Kodiak Island, with headquarters in nearby King Salmon, about 290 miles (470 km) southwest of Anchorage. The area was first designated a national monument in 1918 to protect the area around the major 1912 volcanic eruption of Novarupta, which formed the Valley of Ten Thousand Smokes, a 40-square-mile (100 km2), 100-to-700-foot-deep pyroclastic flow. The park includes as many as 18 individual volcanoes, seven of which have been active since 1900.
Waterton Lakes National Park is a national park located in the southwest corner of Alberta, Canada. It borders Glacier National Park in Montana, United States. Waterton was the fourth Canadian national park, formed in 1895 and named after Waterton Lake, in turn after the Victorian naturalist and conservationist Charles Waterton. Its range is between the Rocky Mountains and prairies. This park contains 505 km2 (195 sq mi) of rugged mountains and wilderness.
Mount Cleveland is the highest mountain in Glacier National Park, located in Montana, United States. It is also the highest point in the Lewis Range, which spans part of the northern portion of the Park and extends into Canada. It is located approximately 3 mi (4.8 km) southeast of the southern end of Waterton Lake, and approximately 5 mi (8.0 km) south of the US/Canada border. The east side of the future national park was purchased by the federal government from the Blackfoot Confederacy in 1895 during the second term of President Cleveland. According to the United States Board on Geographic Names, the mountain is named for the former president.
Inyo National Forest is a United States National Forest covering parts of the eastern Sierra Nevada of California and the White Mountains of California and Nevada. The forest hosts several superlatives, including Mount Whitney, the highest point in the contiguous United States; Boundary Peak, highest point in Nevada; and the Ancient Bristlecone Pine Forest that protects the oldest trees in the world. The forest, encompassing much of Owens Valley, was established by Theodore Roosevelt as a way of sectioning off land to accommodate the Los Angeles Aqueduct project in 1907, making the Inyo National Forest one of the least wooded forests in the United States' system.
Mount Hector is a 3,394-metre (11,135-foot) mountain summit located in the Bow River valley of Banff National Park, in the Canadian Rockies of Alberta, Canada. The mountain was named in 1884 by George M. Dawson after James Hector, a geologist on the Palliser expedition. The mountain is located beside the Icefields Parkway, 17 km (11 mi) north of Lake Louise.
The Nantahala National Forest, established in 1920, is a national forest located in the American state of North Carolina. The word "Nantahala" is a Cherokee word meaning "Land of the Noonday Sun." The name is appropriate as, in some spots, the sun only reaches the floors of the deep gorges of the forest when high overhead at midday. The Spanish Conquistador Hernando de Soto explored the area in 1540, as did William Bartram in the 18th century. The Nantahala River flows through the Nantahala National Forest.

Mount Triumph is a summit in the North Cascades range of Washington state. Located approximately 5.5 miles (8.9 km) west-northwest of the town of Newhalem, it was named by Lage Wernstedt, a surveyor with the U.S. Forest Service. A significant peak in North Cascades National Park, Mount Triumph is one of its "outstanding sights" and is well known among regional climbers for its lack of easy climbing routes to the summit. Despite its moderate elevation, its local relief is dramatic. With the terrain deeply dissected by the valleys of Bacon Creek on the west and Goodell Creek on the east, it rises 1 mile (1.6 km) in less than 2 miles (3.2 km) on the latter side.
