United States Travel Podcast with Harper Wells
Hosted by Harper Wells — a new episode every day from United States.
This podcast approaches travel in the United States as a matter of settling somewhere long enough to understand it. The country is vast central plains, western mountains, eastern hills and low mountains, plus Alaska and Hawaii’s volcanic terrain. That range makes each relocation a shift in climate and habit as much as geography.
Her route takes in real range: Chicago and the Great Lakes, the Rocky Mountain front, the arid Great Basin of the southwest, and the low mountain country of the east. She also treats Washington, D.C. as a working capital rather than a postcard. Each location is chosen for how it connects to the last.
The podcast follows a slower rhythm. Harper returns to places as seasons change, watching how a city like Houston feels in January and July, or how a mountain valley reveals itself after rain. Over time, listener and host build a layered mental map of the country that no single trip could provide.

Natural hazards
Tsunamis; volcanoes; earthquake activity around Pacific Basin; hurricanes along the Atlantic and Gulf of America coasts; tornadoes in the Midwest and Southeast; mud slides in California; forest fires in the west; flooding; permafrost in northern Alaska is a major impediment to development
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"
Note
Note 1: world's third-largest country by size (after Russia and Canada) and by population (after China and India); Mt. McKinley is the highest point (6,190 m; 20,308 ft) in North America, and Death Valley is the lowest point (-86 m; -282 ft)
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
Note 6: Bracken Cave outside San Antonio, Texas is the world's largest bat cave and the summer home to the largest colony of bats in the world; an estimated 20 million Mexican free-tailed bats roost in the cave from March to October, making it the world's largest known concentration of mammals

Background and government
Background
Thirteen of Britain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added as the nation expanded across the North American continent and acquired a number of overseas possessions. Two of the most traumatic experiences in the nation's history were the Civil War (1861-65), in which a northern Union of states defeated a secessionist Confederacy of 11 southern slave states, and the Great Depression of the 1930s, an economic downturn during which about a quarter of the labor force lost its jobs. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. Since the end of World War II, the economy has achieved relatively steady growth, low unemployment, and rapid advances in technology.
