Geyser in Yellowstone Lake

This is a list of lists of active and extinct volcanoes sorted by country. There are separate lists of Antarctic, submarine, and extraterrestrial volcanoes.

A list of volcanoes in United States of America and its territories.

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core-mantle boundary, 3,000 km deep in the Earth.

The Yellowstone Caldera is the volcanic caldera located in Yellowstone National Park in the United States, sometimes referred to as the Yellowstone Supervolcano. The caldera is located in the northwest corner of Wyoming, in which the vast majority of the park is contained. The major features of the caldera measure about 34 by 45 miles (55 by 72 km).

This is a list of UNESCO World Heritage Sites in the Americas (North America, Central America, South America, and the Caribbean). Hawaii and Easter Island are included here given their political ties to the Americas despite being geographically located in Oceania. On the other hand, Greenland has been included here as part of North America despite of its cultural and political associations with Europe. Mexico leads the Americas hosting 31 sites, and is ranked the fourth in the world.

A UNESCO World Heritage Site is a place (such as a forest, mountain, lake, desert, monument, building, complex, or city) that is listed by the UNESCO as of special cultural or physical significance. The list is maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee, composed of 21 states parties which are elected by their General Assembly.

The program catalogues, names, and conserves sites of outstanding cultural or natural importance to the common heritage of humanity. Under certain conditions, listed sites can obtain funds from the World Heritage Fund. The programme was founded with the Convention Concerning the Protection of World Cultural and Natural Heritage, which was adopted by the General Conference of UNESCO on November 16, 1972. Since then, 186 states party have ratified the convention.

As of 2011^[update], 936 sites are listed: 725 cultural, 183 natural, and 28 mixed properties, in 153 States Parties. Italy is home to the greatest number of World Heritage Sites to date with 47 sites inscribed on the list. UNESCO references each World Heritage Site with an identification number; but new inscriptions often include previous sites now listed as part of larger descriptions. As a result, the identification numbers exceed 1200 even though there are fewer on the list.

Yellowstone National Park, established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872, is a national park located primarily in the U.S. state of Wyoming, although it also extends into Montana and Idaho. Yellowstone, widely held to be the first national park in the world, is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. It has many types of ecosystems, but the subalpine forest is dominant.

Native Americans have lived in the Yellowstone region for at least 11,000 years. The region was bypassed during the Lewis and Clark Expedition in the early 19th century. Aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. The U.S. Army was commissioned to oversee the park just after its establishment. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than 1,000 archaeological sites.

The Americas, or America, are lands in the Western hemisphere, also known as the New World.

In the English language, the Americas refers to the landmasses of North America and South America with their associated islands and regions, while America refers almost exclusively to the United States of America.

The Americas cover 8.3% of the Earth's total surface area (28.4% of its land area) and contain about 13.5% of the human population (about 900 million people).

The United States of America (also called the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity).

North America (Spanish: América del Norte or Norteamérica; French: Amérique du Nord; Dutch: Noord-Amerika; Papiamento: Nort Amerika; Kalaallisut: Amerika Avannarleq) is a continent wholly within the Northern Hemisphere and almost wholly within the Western Hemisphere. It is also considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America, and to the west and south by the Pacific Ocean.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people. It is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe.

Yellowstone Lake is the largest body of water in Yellowstone National Park, The lake is 7,732 feet (2,376 m) above sea level and covers 136 square miles (350 km²) with 110 miles (177 km) of shoreline. While the average depth of the lake is 139 feet (42 m) its deepest spot is at least 390 feet (118 m). Yellowstone Lake is the largest freshwater lake above 7,000 feet (2,133 m) in North America.

In winter, ice nearly 3 feet (1 m) thick covers much of the lake, except where shallow water covers hot springs. The lake freezes over by early December and can remain frozen until late May or early June.

Fishing Cone is a geyser in the West Thumb Geyser Basin of Yellowstone National Park in the United States.

In the earlier part of the 20th century, this cone had eruptions as high as 40 feet (12 m). As the water level in Yellowstone Lake has increased, the cone is now inundated during the spring and the temperatures in the cone have cooled enough that it no longer erupts and is now considered a hot spring.

The name Fishing Cone can be traced back to tales told by mountain men of a lake where you could catch a fish then immediately dunk it into hot spring and cook it on the hook. A member of the 1870 Washburn-Langford-Doane Expedition popularized this feat.

William Trumbell, a member of the Washburn party, wrote about the fishing cone in his account of the expedition:

In Henry Winser's The Yellowstone National Park - A Manual for Tourists (1883) he described using hot springs to cook trout:

Park visitors used to be allowed to fish off the cone but this activity is now prohibited.
