Climate
note: note: many consider Mount McKinley, the highest peak in the United States, to be the world’s coldest mountain because of its combination of high elevation and its subarctic location at 63 degrees north latitude; permanent snow and ice cover over 75 percent of the mountain, and enormous glaciers, up to 45 miles long and 3,700 feet thick, spider out from its base in every direction; it is home to some of the world’s coldest and most violent weather, where winds of over 150 miles per hour and temperatures of -93˚F have been recorded.
Terrain
Elevation
lowest point: Death Valley (lowest point in North America) -86 m
mean elevation: 760 m
note: note 1: Mount McKinley is one of the most striking features on the entire planet; at 20,310 feet, it is the crowning peak of the Alaska Range and the highest mountain on North America; it towers three and one-half vertical miles above its base, making it a mile taller from base to summit than Mt. Everest; McKinley's base sits at about 2,000 feet above sea level and rises over three and one-half miles to its 20,310 foot summit; Everest begins on a 14,000-foot high plain, then summits at 29,028 feet
note 2: the peak of Mauna Kea (4,207 m above sea level) on the island of Hawaii rises about 10,200 m above the Pacific Ocean floor; by this measurement, it is the world's tallest mountain -- higher than Mount Everest (8,850 m), which is recognized as the tallest mountain above sea level

Natural hazards
volcanism: volcanic activity in the Hawaiian Islands, Western Alaska, the Pacific Northwest, and in the Northern Mariana Islands; Mauna Loa (4,170 m) in Hawaii and Mount Rainier (4,392 m) in Washington have been deemed Decade Volcanoes by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; Pavlof (2,519 m) is the most active volcano in Alaska's Aleutian Arc and poses a significant threat to intercontinental air travel; St. Helens (2,549 m), famous for the devastating 1980 eruption, remains active today; other historically active volcanoes are mostly concentrated in the Aleutian arc and Hawaii, including (in Alaska) Aniakchak, Augustine, Chiginagak, Fourpeaked, Iliamna, Katmai, Kupreanof, Martin, Novarupta, Redoubt, Spurr, Wrangell, Trident, Ugashik-Peulik, Ukinrek Maars, Veniaminof, (in Hawaii) Haleakala, Kilauea, Loihi, (in the Northern Mariana Islands) Anatahan, (in the Pacific Northwest) Mount Baker, and Mount Hood; see note 2 under "Geography - note"
Geography - note
note 2: the western US coast and the southern coast of Alaska lie along the Ring of Fire, which is a belt bordering the Pacific Ocean that contains about 75% of the world's volcanoes and up to 90% of the world's earthquakes
note 3: the Aleutian Islands are a chain of volcanic islands that divide the Bering Sea (north) from the main Pacific Ocean (south); they extend about 1,800 km (1,118 mi) westward from the Alaskan Peninsula; the archipelago consists of 14 larger islands, 55 smaller islands, and hundreds of islets; there are 41 active volcanoes on the islands, which together form a large northern section of the Ring of Fire
note 4: Mammoth Cave, in west-central Kentucky, is the world's longest known cave system with more than 650 km (405 miles) of surveyed passageways, which is nearly twice as long as the second-longest cave system, the Sac Actun underwater cave in Mexico (see "Geography - note" under Mexico)
note 5: Kazumura Cave on the island of Hawaii is the world's longest and deepest lava-tube cave; it has been surveyed at 66 km (41 mi) long and 1,102 m (3,614 ft) deep

Congress officially created the US military in September 1789; the US Army was established in June 1775 as the Continental Army; after the declaration of independence in July 1776, the Continental Army and the militia in the service of Congress became known collectively as the Army of the United States; when Congress ordered the Continental Army to disband in 1784, it retained a small number of personnel that would form the nucleus of the 1st American Regiment for national service formed later that year; both the US Navy and the US Marines were also established in 1775, but the Navy fell into disuse after the Revolutionary War, and was reestablished by Congress in 1794; the first US military unit devoted exclusively to aviation began operations in 1913 as part of the US Army; the Army Air Corps (AAC) was the US military service dedicated to aerial warfare between 1926 and 1941; the AAC became the US Army Air Forces in 1941 and remained as a combat arm of the Army until the establishment of the US Air Force in 1947 (2025)

Climate
note: note: many consider Mount McKinley, the highest peak in the United States, to be the world’s coldest mountain because of its combination of high elevation and its subarctic location at 63 degrees north latitude; permanent snow and ice cover over 75 percent of the mountain, and enormous glaciers, up to 45 miles long and 3,700 feet thick, spider out from its base in every direction; it is home to some of the world’s coldest and most violent weather, where winds of over 150 miles per hour and temperatures of -93˚F have been recorded.
