Spearfish, South Dakota
Spearfish (Lakota: ''Hočhápȟe'') is a city in Lawrence County, South Dakota. The population was 12,193 at the time of the 2020 census. History Before the Black Hills Gold Rush of 1876, the area was used by Native Americans (primarily bands of Sioux but others also ranged through the area). Once the gold rush started, the city was founded in 1876 at the mouth of Spearfish Canyon, and was originally called Queen City. Spearfish grew as a supplier of foodstuffs to the mining camps in the hills. Even today, a significant amount of truck farming and market gardening still occurs in the vicinity. In 1887, the accepted history of gold mining in the Black Hills was thrown into question by the discovery of what has become known as the Thoen Stone. Discovered by Louis Thoen on Lookout Mountain, the stone purports to be the last testament of Ezra Kind who, along with six others, entered the Black Hills in 1833, "got all the gold we could carry" in June 1834, and were subsequently "kil ...

Spearfish Formation
The Spearfish Formation is a geologic formation, originally described from the Black Hills region of South Dakota, United States, but also recognised in North Dakota, Wyoming, Montana and Nebraska. It is a heterogeneous red bed formation, commonly with siltstone and gypsum low in the formation and sandstone and shale higher up. Other rock types include claystone, conglomerate, dolomite, and oil shale.Sabel, J. M. 1984. Sedimentology and depositional history of the Permo-Triassic Spearfish Formation, southwestern Black Hills, South Dakota. Pages 295-307 in Goolsby, J. and D. Morton, editors. The Permian and Pennsylvanian geology of Wyoming. Wyoming Geological Association, Casper, WY. Guidebook 35. It is typically regarded as Permian–Triassic in age, although its original description included Jurassic rocks. The Spearfish Formation is interpreted as representing shallow marine to coastal terrestrial deposition, like the modern Persian Gulf.Sabel, J. M. 1983. Sedimentology of Spe ...

Spearfish Fisheries Center
The D.C. Booth Historic National Fish Hatchery and Archives, also known as the Spearfish Fisheries Center or Spearfish Fisheries Complex and formerly known as the Spearfish National Fish Hatchery, is one of 70 fish hatcheries that were opened by the U.S. Fish and Wildlife Service as part of the National Fish Hatchery System. The hatchery was established near Spearfish, South Dakota in 1896, with the purpose of introducing and establishing populations of trout in the Black Hills of South Dakota and Wyoming. It is one of the oldest fish hatcheries in the United States and is the second-oldest in the American West. The hatchery spawns and releases about 20,000 to 30,000 rainbow trout each year. The hatchery doubles as a fisheries archive with the purpose of preserving records and early historical artifacts. It is listed on the National Register of Historic Places. Buildings and exhibits The Von Bayer Museum of Fish Culture is located inside the original 1899 hatchery building, as w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spearfish Torpedo
The Spearfish torpedo (formally Naval Staff Target 7525) is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo. It is one of the most advanced torpedoes in the world. Design The torpedo is driven by a pump-jet coupled to a Hamilton Sundstrand 21TP04 gas turbine engine using Otto fuel II and hydroxyl ammonium perchlorate as oxidiser. The addition of an oxidiser improves the specific energy of the fuel by reducing the fuel-richness of the Otto fuel. The Spearfish, which are capable of travelling at , were designed to catch high-speed, deep-diving Soviet threats such as the . A microprocessor enables the torpedo to make autonomous tactical ...

Fairey Spearfish
The Fairey Spearfish was a British Carrier-based aircraft, carrier-based, single-engined, torpedo bomber/dive bomber that was ordered from Fairey Aviation for the Fleet Air Arm during World War II. Designed during the war, the prototype did not fly until July 1945. Much larger than earlier naval bombers, it was designed for use aboard the large s that were cancelled after the war and was itself cancelled thereafter. Seven prototypes were ordered, but only five were built, of which four actually flew. They were mostly used for experimental work until the last aircraft was scrapped in 1952. Design and development The Spearfish was designed by Fairey Aviation to British Admiralty, Admiralty List of Air Ministry specifications#1940–1949, Specification O.5/43 as a replacement for the Fairey Barracuda in the torpedo/dive bomber role. In comparison to the Barracuda, the Spearfish had a much more powerful engine, an internal weapons bay and a retractable ASV radar, ASV Mk.XV surface ...
