Ashfork-Bainbridge Steel Dam
The Ashfork Bainbridge Steel Dam, the first large steel dam in the world, and one of only three ever built in the United States, was constructed in 1898 by the Atchison, Topeka and Santa Fe Railway (ATSF) to supply water for railway operations near Ash Fork, Arizona. It is named for the town of Ash Fork, and for Francis H. Bainbridge, a civil engineer and graduate of Rensselaer Polytechnic Institute (RPI), a member of the Rensselaer Society of Engineers, and an engineer for ATSF. The dam has been listed on the National Register of Historic Places since 1976. Background The ATSF and other railroads had to make special provisions for water supply in desert conditions, as non condensing steam locomotives consumed a prodigious amount of water. The usual approach was to construct a dam to retain surface water, or to drill a series of wells, and store the water in a water tank. Railroad communities often grew up around these reservoirs or water stops. Ash Fork had been such a town fr ...

Coconino County, Arizona
Coconino County is a county in the north-central part of the U.S. state of Arizona. Its population was 145,101 at the 2020 census. The county seat is Flagstaff. The county takes its name from ''Cohonino'', a name applied to the Havasupai people. It is the second-largest county by area in the contiguous United States, behind San Bernardino County, California. It has , or 16.4% of Arizona's total area, and is larger than each of the nine smallest states in the U.S. Coconino County comprises the Flagstaff metropolitan statistical area, Grand Canyon National Park, the federally recognized Havasupai Nation, and parts of the federally recognized Navajo, Hualapai, and Hopi nations. As a result, its relatively large Native American population makes up nearly 30% of the county's total population; it is mostly Navajo, with smaller numbers of other tribes. The county was the setting for George Herriman's early 20th-century ''Krazy Kat'' comic strip. History After European America ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carb ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kaibab National Forest
At 1.6 million acres (650,000 ha) the Kaibab National Forest borders both the north and south rims of the Grand Canyon, in north-central Arizona. It is divided into three major sections: the ''North Kaibab Ranger District'' (offices in Fredonia) and the South Kaibab and are managed by the United States Forest Service. The South Kaibab is further divided into two districts, the ''Tusayan Ranger District'' (offices in the Grand Canyon), and the ''Williams Ranger District'' (offices in Williams). Grand Canyon National Park separates the North Kaibab and the South Kaibab. The South Kaibab covers and the North Kaibab stretches over . Elevations vary on the forest from 5,500 feet (1,676 m) in the southwest corner to 10,418 feet (3,175 m) at the summit of Kendrick Peak on the Williams Ranger District. The forest as a whole is headquartered in Williams. North Kaibab The Kaibab Plateau is an island surrounded by lower elevations. The plateau, with elevation up to 9,215 feet (2,800 ...

Hauser Lake Dam
Hauser Dam (also known as Hauser Lake Dam) is a Hydroelectricity, hydroelectric straight Dam#Gravity dams, gravity dam on the Missouri River about northeast of Helena, Montana, in the United States. The original dam, built between 1905 and 1907, failed in 1908 and caused severe flooding and damage downstream. A second dam was built on the site in 1908 and opened in 1911 and comprises the present structure. The current Hauser Dam is long and high.''Upper Missouri River Reservoir Fisheries Management Plan, 2010–2019'', Montana Department of Fish, Wildlife and Parks, May 13, 2010, p. 11.

Redridge Steel Dam
The Redridge Steel Dam is a steel dam across the Salmon Trout River in Redridge, Houghton County, Michigan. Completed in 1901, it is a flat slab buttress dam constructed of steel, a relatively rare material for construction of dams, which are typically made of earthenworks, concrete, or masonry. Most sources indicate that it was one of only three such dams constructed in the United States, the other two being the Ashfork-Bainbridge Steel Dam (1898, Arizona) and the Hauser Lake Dam (1907, Montana), the last of which failed within a year of construction. History In 1894, prior to the construction of the steel dam, the Atlantic Mining Company built a timber crib dam across the Salmon Trout River. The dam created a reservoir which supplied water to the Atlantic stamp mill which extracted copper from ore-bearing rock. With the growth of the Atlantic stamp mill and the construction of the Baltic Mining Company mill nearby, this reservoir proved to be insufficient, and in 1901 the ...

Overtop
A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release. Between the years 2000 and 2009 more than 200 notable dam failures happened worldwide. A dam is a barrier across flowing water that obstructs, that directs or slows down the flow, often creating a reservoir, lake or impoundments. Most dams have a section called a '' spillway or weir'' over or through which water flows, either intermittently or continuously, and some have hydroelectric power generation systems installed. Dams are considered "installations containing dangerous forces" under International humanitarian law due to the massive impact of a possible destruction on the civilian population and the environment. Dam failures are comparatively rare, but can cause immense damage and loss of life when they occur. In 1975 the failure of the Banqiao Reservoir Dam and other ...

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a stru ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wisconsin Bridge And Iron Company
The Wisconsin Bridge and Iron Company (WB&I) was a fabricator and erector of iron and steel bridges and other large structures. According to one source it was founded in Milwaukee, Wisconsin in 1888. According to another source, the firm was founded by three brothers in Wauwatosa, Wisconsin in 1870 as Weinhagen Brothers, Engineers, which in 1880 became known as the Wisconsin Bridge and Iron Company, and was incorporated in 1891 using that name. The 1887 Turtleville bridge was believed to be one of the earlier truss bridges constructed by the firm. The Riemer family of Elm Grove, Wisconsin was heavily affiliated with the company until it was sold in the 1970s. A competitor to American Bridge Company, (in at least one case both firms submitted bids that matched to the penny), this firm was responsible for many bridges and other large structures in the United States Midwest and elsewhere. The Historic American Engineering Record shows at least 16 projects where WB&I were believed ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

Grand Canyon Railway
The Grand Canyon Railway is a heritage railroad which carries passengers between Williams, Arizona, and the South Rim of Grand Canyon National Park. The railroad, built by the Atchison, Topeka and Santa Fe Railway, was completed on September 17, 1901. The arrival of trains led increased tourism to the area, and the railway company was instrumental in the creation of the Grand Canyon Village to serve guests. Declining ridership due to the popularity of the automobile led the Atchison, Topeka and Santa Fe Railway to cease passenger service of the Grand Canyon Railway in July 1968 and freight service on the line ended in 1974. Private investors purchased the line in 1988, restored the facilities, and started running passenger trains again on September 17, 1989. Today, the railroad carries hundreds of passengers to and from the canyon every day and operates year-round. The entire Grand Canyon Railway has been added to the National Register of Historic Places, recognizing the cont ...
