Tubing (recreation)
Tubing, also known as inner tubing, bumper tubing, towed tubing, or kite tubing, is a recreational activity where an individual rides on top of an inner tube, either on water, snow, or through the air. The tubes themselves are also known as "donuts" or "biscuits" due to their shape. Variations Water Tubing on water generally consists of two forms: towed and free-floating, also known as river tubing. There is also water skiing. According to ''Time Magazine'', tubing was purportedly invented on the Black River in Missouri by Jan & Harriet Wright of Poplar Bluff, MO sometime in the middle of the 20th century, but examples of the practice were published as early as 1916, when the popularization of the automobile meant a large supply of rubber inner tubes was available to the general public. Towed tubing usually takes place on a large body of water such as a lake or river. One or more tube riders (often called "tubers") tether their tubes to a powered watercraft such as a motor ...

Arrowrock Dam
Arrowrock Dam is a concrete arch dam in the western United States, on the Boise River in southwestern Idaho, east of Boise. Opened in 1915, it is located on the border of Boise and Elmore counties, upstream of the Lucky Peak Dam and reservoir. The spillway elevation for Arrowrock is above sea level and its primary purpose is to provide irrigation water for agriculture. The dam was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 2016, and is operated by the U.S. Bureau of Reclamation. Preparations In 1910, the Reclamation Service began to consider another storage facility farther east on the Boise River. After several surveys, engineers decided upon the Arrowrock site which had previously been the site of a private irrigation venture under the direction of Arthur De Wint Foote yet failed for lack of funding. The Arrowrock site is at the confluence of the main channel and the south fork. That was to be the most amb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Lowell
Deer Flat Upper Embankment (National ID # ID00276) is a dam in the western United States in southwestern Idaho. Located in the Treasure Valley in Canyon County, it is directly southwest of Nampa. The earthen dam was completed in 1908 by the Reclamation Service (now U.S. Bureau of Reclamation), with a height of and a crest length of . The Upper Embankment is the largest of a set of four dikes here impounding the water of the Boise River in offstream storage. The other dams are: *Deer Flat Middle Dike (ID #ID00277), completed 1911, high, long *Deer Flat Lower Dike (ID #ID00278), completed 1908, high, long *Deer Flat East Dike (ID #ID82902), completed 1911, high, long The reservoir it creates, Lake Lowell, has a normal surface area of , and a maximum capacity of 169,000 acre-feet. Its surface elevation is approximately above sea level. The Boise Project was among the first undertaken by the Reclamation Service after its formation in 1902. Shortly before leavi ...

Boise River Diversion Dam
The Boise River Diversion Dam is a diversion dam in the western United States, on the Boise River in southwestern Idaho. southeast and upstream of Boise in Ada County, it was completed in 1909 and is operated by the U.S. Bureau of Reclamation. The diverted water fills the concrete New York Canal, the primary irrigation channel for Ada and Canyon counties in the Treasure Valley. Several miles upstream of the Diversion Dam is Lucky Peak Dam. Completed in 1955, it was built and is operated by the U.S. Army Corps of Engineers. Construction In March 1906, the Utah Fire Proofing Company began work on the Boise River Diversion Dam with the provision that the structure would be completed within one year. It soon became apparent that the dam would not be finished on time. With little experience in such endeavors, Utah Fire Proofing failed to provide adequate foremen for the project. At least nineteen superintendents worked on the dam and their incompetence led to an extraordinar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucky Peak Dam
Lucky Peak Dam is a rolled earth and gravel fill embankment dam in the western United States, located on the Boise River in southwestern Idaho. In Ada County east of Boise, it is directly downstream of Arrowrock Dam, a concrete arch dam completed in 1915. At the time of its construction in the early 1950s, Lucky Peak's primary purpose was flood control, with a secondary purpose of The normal operating elevation of the full reservoir is above sea level, the empty reservoir's elevation (Boise River) is Construction began in November 1949 by the U.S. Army Corps of Engineers; many men were lost blasting the mountain. Most had no experience with dynamite. They brought in Clifford Riddle who was an expert in dynamite. Clifford had settled his wife and sons in the Boise Valley. Clifford carved the crucial operational curve of the road to reach the reservoir called Lucky Peak Lake. Most of the federal dams in southern Idaho, including the others on the Boise River, were buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idaho State Highway 21
State Highway 21 (SH-21), also known as the Ponderosa Pine Scenic Byway, is a state highway in Idaho. It runs from Boise to Stanley, primarily as a two-lane road. With two-thirds of its length in Boise County, it passes by historic Idaho City and the village of Lowman to the western edge of the Sawtooth Mountains, then along their northern boundary to Stanley. The road is designated as one of Idaho's scenic byways and provides access to Sawtooth National Recreation Area from Boise and the Treasure Valley. It primarily follows the Boise River and its tributary Mores Creek to the Boise Basin and beyond, and then the upper South Fork of the Payette River and a tributary from Lowman to Banner Creek Summit. Route description SH-21 begins at exit 57 of Interstate 84 southeast of Boise, exactly above sea level. The highway is an eastern extension of Gowen Road, which runs along the southern and western perimeter of the Boise Airport (and the Air National Guard's Gowen Fiel ...

Basalt
Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sawtooth National Forest
Sawtooth National Forest is a National Forest that covers 2,110,408 acres (854,052 ha) in the U.S. states of Idaho (~96 percent) and Utah (~4 percent). Managed by the U.S. Forest Service in the U.S. Department of Agriculture, it was originally named the Sawtooth Forest Reserve in a proclamation issued by President Theodore Roosevelt on May 29, 1905. On August 22, 1972 a portion of the forest was designated as the Sawtooth National Recreation Area (SNRA), which includes the Sawtooth, Cecil D. Andrus–White Clouds, and Hemingway–Boulders wilderness areas. The forest is managed as four units: the SNRA and the Fairfield, Ketchum, and Minidoka Ranger Districts. Sawtooth National Forest is named for the Sawtooth Mountains, which traverse part of the SNRA. The forest also contains the Albion, Black Pine, Boise, Boulder, Pioneer, Raft River, Smoky, Soldier, Sublett, and White Cloud mountain ranges, as well as Hyndman Peak, the ninth-highest point in Idaho at above s ...
