Melipeuco (] ) is a town and commune (Spanish: "comuna" ) in Chile, located at the foot of the Andes, in the Province of Cautín, Araucanía Region.
 Melipeuco is 12 km from the southern entrance of the Conguillío National Park.
 The Nevados de Sollipulli, an ice-filled volcanic caldera surrounded by numerous hot water springs and geysers, lie south of the town.
 Lake Carilafquén is also located in this area.
 At the edge of the Nevados de Collipulli, at the Alpehue intersection 33 km away, there are several hot springs with water from 40 to , even in the middle of glacier blocks.
The establishment of Grand Teton National Park took place over a period spanning more than 50 years.
 Located in the northwestern region of the U.S. state of Wyoming, Grand Teton National Park is 10 mi south of Yellowstone National Park which was established in 1872, when Wyoming, Idaho and Montana were still territories and the region was very sparsely settled.
 By the late 19th century, conservationists were working to provide further protection to surrounding regions, leading President Grover Cleveland to create the Teton Forest Reserve, which included a portion of northern Jackson Hole.
 By 1902, the reserve had been combined into the Yellowstone Forest Reserve, then was divided again in 1908 by President Theodore Roosevelt, establishing the Teton National Forest, which protected most of the Teton Range.
 By 1907, the U.S. Bureau of Reclamation had constructed a temporary dam at the Snake River outlet of Jackson Lake.
 This dam failed in 1910 and a new concrete Jackson Lake Dam replaced it by 1911.
 The dam was further enlarged in 1916, raising lake waters 39 ft as part of the Minidoka Project, designed to provide irrigation for agriculture in the state of Idaho.
 Though efforts to protect the Teton Range and Jackson Hole as part of an expanded Yellowstone National Park dated back to the late 19th century, proposals to construct more dams on some of the other lakes in Jackson Hole led Yellowstone National Park superintendent Horace Albright to block such efforts.
 Albright was originally an advocate of the expanded Yellowstone plan which was very unpopular with local residents.
 By the mid-1920s local sentiment had changed as a result of proposals for a new national park including only the Teton Range and six lakes at the base of the range.
 With the general agreement of prominent Jackson Hole residents to this plan, President Calvin Coolidge signed the executive order establishing the 96000 acre Grand Teton National Park on February 26, 1929.
Fan and Mortar Geysers are two geysers in the Upper Geyser Basin in Yellowstone National Park.
 For the past several decades, they have erupted in concert with one another and are generally talked about together.
 The records detailing these geysers' known eruptive history shows that they have been infrequent and irregular performers.
The United States Park Police (USPP) is one of the oldest uniformed federal law enforcement agencies in the United States.
 It functions as a full-service law enforcement agency with responsibilities and jurisdiction in those National Park Service areas primarily located in the Washington, D.C., San Francisco, and New York City areas and certain other government lands.
 The United States Park Police is one of the few full-service police departments in the federal government that possess both state and federal authority.
 In addition to performing the normal crime prevention, investigation, and apprehension functions of an urban police force, the Park Police are responsible for policing many of the famous monuments in the United States.
 The USPP shares law enforcement jurisdiction in all lands administered by the National Park Service with a force of National Park Service Rangers tasked with the same law enforcement powers and responsibilities.
 The agency also provides protection for the President, Secretary of the Interior, and visiting dignitaries.
 The Park Police is a unit of the National Park Service, which is a bureau of the Department of the Interior.
Morne Trois Pitons National Park is a World Heritage Site (since 1997) located in Dominica.
 This area was established as a national park by the Dominican government in July 1975, the first to be legally established in the country.
 The National Park is named after its highest mountain, Morne Trois Pitons, meaning mountain of three peaks.
 The park is a significant area of volcanic activity.
 Features within the part include the Valley of Desolation, a region of boiling mud ponds and small geysers; the Boiling Lake, Titou Gorge, and Emerald Pool.
Grotto Geyser is a fountain-type geyser located in the Upper Geyser Basin in Yellowstone National Park in the United States.
 Grotto Geyser is the namesake for the group of geysers that includes Grotto Fountain Geyser, South Grotto Fountain Geyser, Indicator Spring, Spa Geyser, and Rocket Geyser.
The Glacier National Park Fund (established in 1999), is an organization whose main goal is to raise money to support the demands of the Glacier National Park, located in West Glacier, Montana.
 According to the National Park Service, the Glacier National Park Fund supports park projects, programs, and services in four areas: to preserve the park experience, to provide curriculum-based instruction, to research the park ecosystem, and to prepare for the 2010 Centennial year of the park.
 The Glacier National Park Fund provided funds for different studies.
 In July 2007, The Glacier National Park Fund funded a study involving human and bear aversion techniques.
 Also, in 2009, The Glacier National Park Fund granted $10,000 to enable biologists to learn more about the Bighorn Sheep that inhabit Glacier National Park, along the park's boundary with the Blackfeet Indian Reservation.
 The Glacier National Park Fund has an official mascot named Billy Bowman.
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.
Yellowstone National Park is a national park located in the U.S. states of Wyoming, Montana, and Idaho.
 It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872.
 Yellowstone was the first National Park in the U.S. and is also widely held to be the first national park in the world.
 The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular features.
 It has many types of ecosystems, but the subalpine forest is the most abundant.
 It is part of the South Central Rockies forests ecoregion.
Bulger Geyser is located in the Upper Geyser Basin of Yellowstone National Park, Wyoming.
 Bulger Geyser is 200 ft south of Grand Geyser.
 It erupts frequently, with both major and minor eruptions.
 As with most geysers, the minor eruptions are the most common.
 They have a duration of seconds.
 Major eruptions are infrequent, but they have durations as long as 12 minutes.
 Either way, the play consists of somewhat vigorous bursting 1–12 feet high.

Question: In what year was the national park in which Fan and Mortar Geysers are located signed into law?
Answer: 1872
