'Railroad tour through the state of Utah... Shows... the mineral resources of Utah, including coal and copper. Director: Carlton T. Sills.'
Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 miles (970 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres (3.0 sq mi; 7.7 km2). It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine. The mine experienced a massive landslide in April 2013 and a smaller slide in September 2013...
History
Minerals, in the form of copper ore, were first discovered in Bingham Canyon in 1848 by two brothers, Sanford and Thomas Bingham, sons of Erastus Bingham, latter-day saint pioneers of September 1847, who grazed their cattle there. They reported their find to their leader, Brigham Young, who advised against pursuing mining operations because the survival and establishment of settlements was of paramount importance at that time. The brothers applied themselves to that purpose as directed and did not stake a claim. In 1850, the Bingham family went to settle what is now Weber County, leaving the canyon still today known by their name...
It was not until September 17, 1863, that extraction of ore began and the potential of the canyon's mineral resources began to be widely recognized. That was when George B. Ogilvie and 23 others "located the West Jordan claim", soon followed by the Vidette claim. At first, mining was confined to placer gold, lead-silver and copper-gold. Porphyry copper required processing and a railroad, which reached the canyon in 1873...

The Denver & Rio Grande Western Railroad (reporting mark DRGW), often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft (914 mm) narrow-gauge line running south from Denver, Colorado in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic.
The Rio Grande was the epitome of mountain railroading, with a motto of Through the Rockies, not around them and later Main line through the Rockies, both referring to the Rocky Mountains. The D&RGW operated the highest mainline rail line in the United States, over the 10,240 feet (3,120 m) Tennessee Pass in Colorado, and the famed routes through the Moffat Tunnel and the Royal Gorge. At its height in the mid-1880s, the D&RG had the largest narrow-gauge railroad network in North America with 2,783 miles (4,479 km) of track interconnecting the states of Colorado, New Mexico, and Utah. Known for its independence, the D&RGW operated the Rio Grande Zephyr until its discontinuation in 1983. This was the last private intercity passenger train in the United States until Brightline (now Virgin Trains USA) began service in Florida in 2018.
In 1988, the Rio Grande's parent corporation, Rio Grande Industries, purchased Southern Pacific Transportation Company, and as the result of a merger, the larger Southern Pacific Railroad name was chosen for identity. The Rio Grande operated as a separate division of the Southern Pacific, until that company was acquired by the Union Pacific Railroad. Today, most former D&RGW main lines are owned and operated by the Union Pacific while several branch lines are now operated as heritage railways by various companies...
