full_context: Document 1: Gladstone, British Columbia: Gladstone is a ghost town located in the Boundary Country region of British Columbia. Gladestone is located near McRae Creek. Today Gladestone is also known as Coryell. In 1898 Gladestone had 3 hotels, 3 stores, a livery stable among other businesses. Gladstone became a town built on mining and the railway. Many prospectors came to the area in order to mine a place called Burnt Basin. By 1899 Gladestone started to decline and eventually became a ghost town.
Document 2: Munson Valley Historic District: Munson Valley Historic District is the headquarters and main support area for Crater Lake National Park in southern Oregon. The National Park Service chose Munson Valley for the park headquarters because of its central location within the park. Because of the unique rustic architecture of the Munson Valley buildings and the surrounding park landscape, the area was listed as a historic district on the National Register of Historic Places (NRHP) in 1988. The district has eighteen contributing buildings, including the Crater Lake Superintendent's Residence which is a U.S. National Historic Landmark and separately listed on the NRHP. The district's NRHP listing was decreased in area in 1997.
Document 3: Major Israel McCreight: Major Israel McCreight (Oglala Lakota: "Cante Tanke" ("Great Heart")(Čhaŋté Tȟáŋka) in Standard Lakota Orthography) (April 22, 1865 – October 13, 1958) is notable in American history as a Progressive Era banker, conservationist and expert on Native American culture and policy. McCreight was a founder of the Pennsylvania Conservation Association, and authored President Theodore Roosevelt’s conservation policy on public education and Cook Forest State Park, the first Pennsylvania State Park acquired to preserve a natural landmark. McCreight dedicated his life to public education about Native American culture and was a nominee for U.S. Commissioner of Indian Affairs. McCreight’s relationship with the Lakota people began as a young man in the Dakota Territory in 1885 when he lived with them during a period of great sorrow. He returned to Du Bois, Pennsylvania, became a successful banker, and led the region into prominence as the biggest bituminous coal producers in the United States between 1890 and World War I. McCreight collaborated with Flying Hawk, an Oglala Lakota Chief, to write a Native American’s view of U.S. history and classic accounts of the Battle of the Little Big Horn, Crazy Horse and commentaries on Native American philosophy. The Wigwam, McCreight’s home in Du Bois, Pennsylvania, was a Native American heritage center and once the Eastern home of Oglala Lakota ""Oskate Wicasa"" Wild Westers. McCreight was a founder of the Pennsylvania Banker’s Association and member of the Pennsylvania Society of New York. McCreight was an ardent student of the Indian, a lover of fair play and an author of books and articles.
Document 4: Lake Crescent: Lake Crescent is a deep lake located entirely within Olympic National Park in Clallam County, Washington, United States, approximately 17 mi west of Port Angeles, Washington on U.S. Route 101 and nearby to the small community of Piedmont. At an official maximum depth of 624 ft , also the maximum depth of the depth sounder used to find that depth (see depth section), it is officially the second deepest lake in Washington. Unofficial depth measurements of more than 1000 ft have been rumored in the region for years, although this figure has recently been proven false after a lake-wide bathymetric survey was performed from 2013 to 2014 by Eian Ray and Jeff Enge. The results of this survey showed the maximum depth as being 596 feet. Using GIS statistical analysis, this survey also showed the lake contains approximately 0.5 cubic miles of fresh water.
Document 5: William Gladstone Steel: William Gladstone Steel (September 7, 1854 – October 21, 1934), called the "father of Crater Lake", referring to the creation of Crater Lake National Park in Oregon, United States. A native of Ohio, he worked in the newspaper business before becoming a mail carrier. He campaigned Congress for 17 years to designate Crater Lake as a national park.
Document 6: William Walker Scranton: William Walker Scranton (April 4, 1844 – December 3, 1916) was an American businessman based in Scranton, Pennsylvania. He became president and manager of the Lackawanna Iron and Coal Company after his father's death in 1872. The company had been founded by his father's cousin George W. Scranton. Among his innovations, Scranton adopted the Bessemer process for his operations in 1876, greatly increasing production of steel ties with a new mill. Scranton founded the Scranton Steel Company, in 1891 consolidated as Lackawanna Iron and Steel Company. The steel company became the second largest in the nation. He later also managed the Scranton Gas and Water Company, developing a secure water supply outside the city by creating Lake Scranton.
Document 7: Crater Lake National Park: Crater Lake National Park is a United States National Park located in southern Oregon. Established in 1902, Crater Lake National Park is the fifth-oldest national park in the U.S. and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of a destroyed volcano, Mount Mazama, and the surrounding hills and forests.
Document 8: Crater Lake: Crater Lake (Klamath: giiwas) is a caldera lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2148 ft -deep caldera that was formed around 7,700 (± 150) years ago
Document 9: Wizard Island: Wizard Island is a volcanic cinder cone which forms an island at the west end of Crater Lake in Crater Lake National Park, Oregon. The top of the island reaches 6933 ft above sea level, about 755 ft above the average surface of the lake. The cone is capped by a volcanic crater about 500 ft wide and 100 ft deep. The crater was named the "Witches Cauldron" by William Gladstone Steel in 1885, who also gave Wizard Island its name at the same time.
Document 10: Sinnott Memorial Observation Station: The Sinnott Memorial Observation Station is a sheltered viewpoint built into the caldera cliff 900 feet above Crater Lake in southern Oregon, United States. It is located near the Rim Village Visitor Center in Crater Lake National Park. The structure includes a small natural history museum with exhibits that highlight the geologic history of Mount Mazama and the formation of Crater Lake. The building was officially dedicated as the Nicholas J. Sinnott Memorial Observation Station and Museum; however, it is commonly known as the Sinnott Memorial Overlook or Sinnott Viewing Area. It is architecturally significant because it was the first National Park Service building constructed specifically as a museum and the first structure built in Crater Lake National Park using rustic stone masonry construction. It is listed on the National Register of Historic Places as Sinnott Memorial Building No. 67.
Document 11: David Steele (minister): David Steele, Sr. (2 November 1803 – 29 June 1887) was a Reformed Presbyterian or Covenanter minister. He was born in Upper Creevagh, Donegal, Ireland to David Steel and Sarah Gailey. His father was a fourth-generation descendant of Capt. John Steel of Lesmahagow, Lanarkshire, Scotland, a local leader in the Covenanter uprising of 1679. His grandparents, on both sides of the family, were Covenanters. His paternal grandfather, John Steel, had resided in Fanet. He moved to Creevaugh sometime prior to the birth of his grandson. His maternal grandfather, Andrew Gailey, resided in Killylastin. His father died when he was an infant, in February, 1805. According to Steele, his only recollection of his father was conducting family worship. Next to the Bible, Steele claimed the greatest impression made on him, in his youth, was Thomas Boston's "Four-fold State of Man" and "A Cloud of witnesses for the royal prerogatives of Jesus Christ". The latter work is an account, published in 1714, of the Scottish martyrs who perished during the persecutions, known as the "Killing Times", during the reigns of Charles II and James VII. In his seventeenth year [1820], he entered the Academy in Londonderry, where he pursued his studies for three years, including the study of languages.
Document 12: Garfield Peak (Oregon): Garfield Peak is a mountain peak on the south end of Crater Lake in Crater Lake National Park, Oregon. The top of the peak reaches 7976 ft above sea level. The peak has a 1000 ft elevation trail to the summit from the Crater Lake lodge, one of the most popular hiking sites surrounding the lake. The 1.7 mile trail continues East toward Applegate peak (7976 ft high). The peak is one of seven peaks on Crater Lake's rim to rise above 8000 ft .
Document 13: Hayden Geological Survey of 1871: The Hayden Geological Survey of 1871 explored the region of northwestern Wyoming that later became Yellowstone National Park in 1872. It was led by geologist Ferdinand Vandeveer Hayden. The 1871 survey was not Hayden's first, but it was the first federally funded, geological survey to explore and further document features in the region soon to become Yellowstone National Park and played a prominent role in convincing the U.S. Congress to pass the legislation creating the park. In 1894, Nathaniel P. Langford, the first park superintendent and a member of the Washburn-Langford-Doane Expedition which explored the park in 1870, wrote this about the Hayden expedition:
Document 14: Mount Okmok: Mount Okmok is the highest point on the rim of Okmok Caldera (Unmagim Anatuu in Aleut) on the northeastern part of Umnak Island in the eastern Aleutian Islands of Alaska. This 5.8 mile (9.3 km) wide circular caldera truncates the top of a large shield volcano. A crater lake once filled much of the caldera, but the lake ultimately drained through a notch eroded in the northeast rim. The prehistoric lake attained a maximum depth of about 150 m (500 ft) and the upper surface reached an elevation of about 475 m (1560 ft), at which point it overtopped the low point of the caldera rim. Small, shallow remnants of the lake remained north of Cone D at an altitude of about 1075 feet: a small shallow lake located between the caldera rim and Cone D; a smaller lake (named Cone B Lake) farther north near the caldera's gate. After the 2008 eruption, the hydrogeology of the caldera was greatly changed with five separate sizable lakes now emplaced. In addition to the caldera lakes, Cone A, Cone E, Cone G and the new 2008 vent on Cone D contain small crater lakes.
Document 15: Crater Lake Lodge: Crater Lake Lodge was built in 1915 to provide overnight accommodations for visitors to Crater Lake National Park in southern Oregon, USA. The lodge is located on the southwest rim of the Crater Lake caldera overlooking the lake 1000 ft below. The lodge is owned by the National Park Service, and is listed on the National Register of Historic Places.
