Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth Mountain. The valley is one of the Earth's largest calderas, measuring about 20 mi (32 km) long (east-west), 11 mi (18 km) wide (north-south), and up to 3,000 ft (910 m) deep.
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma or by circulation through faults to hot rock deep in the Earth's crust.
The geothermal areas of Yellowstone include several geyser basins in Yellowstone National Park as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. A study that was completed in 2011 found that a total of 1,283 geysers have erupted in Yellowstone, 465 of which are active during an average year. These are distributed among nine geyser basins, with a few geysers found in smaller thermal areas throughout the Park. The number of geysers in each geyser basin are as follows: Upper Geyser Basin (410), Midway Geyser Basin (59), Lower Geyser Basin (283), Norris Geyser Basin (193), West Thumb Geyser Basin (84), Gibbon Geyser Basin (24), Lone Star Geyser Basin (21), Shoshone Geyser Basin (107), Heart Lake Geyser Basin (69), other areas (33). Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them.
Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate. Because of the huge amount of geothermal vents, travertine flourishes. Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.
The geothermal areas in Lassen Volcanic National Park include several groups of hot springs and fumaroles, as remnants of former volcanic activity, exist in Lassen Volcanic National Park in northeastern California. Most of these lie in or are closely adjacent to Mount Tehama's caldera. Bumpass Hell is the most spectacular of these, but others of importance are Sulphur Works, Little Hot Springs Valley, Boiling Springs Lake and Devil's Kitchen. In each thermal area, the highest temperature of water generally is close to the boiling temperature at the altitude of the particular spring or fumarole — 198 °F (92 °C) at Bumpass Hell and 191 °F (88 °C) on the northwest flanks of Lassen Peak. Temperatures as high as 230 °F (110 °C) have been recorded in the park.
Beitou District is the northernmost of the twelve districts of Taipei City, Taiwan. The historical spelling of the district is Peitou. The name originates from the Ketagalan word Kipatauw, meaning witch. Beitou is the most mountainous and highest of Taipei's districts, encompassing a meadow with rivers running through the valley which have abundant steam rising from them; the result of geothermal warming. The valley is often surrounded by mist shrouding the trees and grass. Beitou is famous for its hot springs. In March 2012, it was named one of the Top 10 Small Tourist Towns by the Tourism Bureau of Taiwan.
The Clark Fork, or the Clark Fork of the Columbia River, is a river in the U.S. states of Montana and Idaho, approximately 310 miles (500 km) long. The largest river by volume in Montana, it drains an extensive region of the Rocky Mountains in western Montana and northern Idaho in the watershed of the Columbia River. The river flows northwest through a long valley at the base of the Cabinet Mountains and empties into Lake Pend Oreille in the Idaho Panhandle. The Pend Oreille River in Idaho, Washington, and British Columbia, Canada which drains the lake to the Columbia in Washington, is sometimes included as part of the Clark Fork, giving it a total length of 479 miles (771 km), with a drainage area of 25,820 square miles (66,900 km2). In its upper 20 miles (32 km) in Montana near Butte, it is known as Silver Bow Creek. Interstate 90 follows much of the upper course of the river from Butte to Saint Regis. The highest point within the river's watershed is Mount Evans at 10,641 feet (3,243 m) in Deer Lodge County, Montana along the Continental Divide.
The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession of caldera-forming eruptions. The resulting calderas include the Island Park Caldera, Henry's Fork Caldera, and the Bruneau-Jarbidge caldera. The hotspot currently lies under the Yellowstone Caldera. The hotspot's most recent caldera-forming supereruption, known as the Lava Creek Eruption, took place 640,000 years ago and created the Lava Creek Tuff, and the most recent Yellowstone Caldera. The Yellowstone hotspot is one of a few volcanic hotspots underlying the North American tectonic plate; another example is the Anahim hotspot.
Yellowstone National Park has over 1,100 miles (1,800 km) of blazed and mapped hiking trails, including some that have been in use for hundreds of years. Several of these trails were the sites of historical events. Yellowstone's trails are noted for various geysers, hot springs, and other geothermal features, and for viewing of bald eagles, ospreys, grizzly bears, black bears, wolves, coyotes, bighorn sheep, pronghorns, and free-ranging herds of bison and elk.

Scovern Hot Springs is a thermal spring system, and former settlement in the Kern River Valley of the Southern Sierra Nevada, in Kern County, California.
Beppu Onsen (別府温泉) is an extensive hot spring system in the city of Beppu, Ōita, Japan. There are eight distinct major thermal spring zones called "Beppu Hatto".
Seminole Hot Springs is an unincorporated community in Los Angeles County, California, United States. Seminole Hot Springs is located in the Santa Monica Mountains near Cornell, 3.6 miles (5.8 km) south-southeast of Agoura Hills at an elevation of 932 feet (284 m).
Bimini Baths was a geothermal mineral water public bathhouse and plunge in what is now Koreatown, Los Angeles, California, US. It was situated just west of downtown, near Third Street and Vermont Avenue. Bimini Baths contained a natatorium, swimming pools, swimming plunge, Turkish baths, a medical treatment department, and bottling works.
Wheeler Springs is an unincorporated community that grew around a set of sulphurated hot springs in Ventura County, California. It is located 6 miles north of the Ojai Valley, within Los Padres National Forest. It is named for Wheeler Blumberg, who founded the town in 1891, and the many natural hot springs.
Jordan Hot Springs is series of thermal mineral springs located in the Golden Trout Wilderness, Inyo National Forest, California.
Frenchman's Hot Springs, also known as Frenchman's Bend Hot Springs or Warfield Hot Springs, is a hot spring located along Warm Springs Creek in the Sawtooth National Forest, 11 miles (17.7km) from Ketchum, Idaho. The springs are composed of three wide, shallow pools. The pools are rock-walled, with sand and gravel covered bottoms. The average temperature of the springs varies throughout the year, but most of the time, water enters the springs at around 124°F (51.11°C). The water in the springs is usually clear.
Silver Creek Hot Spring is a geothermal mineral spring in Valley County, Idaho. It is located 23 miles North of the town of Crouch. The hot spring is also known as the Silver Creek Plunge. The spring flows into Silver Creek, and on to Middle Fork, a tributary of the Payette River.
