Utah Verbiage
https://utahrails.net/bingham/bingham-copperfield-vehicle-tunnel.html On February 1939, the Bingham-Copperfield vehicular tunnel opened, connecting the town of Bingham with the town of Copperfield…The tunnel underground route curved to the east, on an alignment that was meant to avoid any future interference with Utah Copper’s mine expansion…The tunnel was 16 feet wide and 18 feet 2 inches high…Traffic in the tunnel was one-way, controlled by “electric eye” that in turn controlled electric traffic signals. Flag men communicating by telephone were used regularly when the traffic lights were not working properly…The tunnel was closed to the public in October 1956…The vehicular tunnel was finally closed to all traffic in mid 1973, and the Bingham portal was buried in July 1973.

Utah Copper mine Kennecott Utah Copper LLC (KUC), https://en.wikipedia.org/wiki/Kennecott_Utah_Copper a division of Rio Tinto Group, is a mining, smelting, and refining company. Its corporate headquarters are located in South Jordan, Utah. Kennecott operates the Bingham Canyon Mine, one of the largest open-pit copper mines in the world in Bingham Canyon, Salt Lake County, Utah. The company was first formed in 1898 as the Boston Consolidated Mining Company. The modern corporation was formed in 1989. The mine and associated smelter produce 1% of the world’s copper. The postcard verbiage says as of 1924, the mine has paid over $125,000,000 in dividends.
Bingham City https://westernmininghistory.com/towns/utah/bingham/ Currently a ghost town of 0 population in southeast Salt Lake County, in a narrow canyon on the eastern face of the Oquirrh Mountains; maximum population was once 15,000 in the 1920s …Bingham Canyon was first settled in 1848 by the Mormon settlers Thomas and Sanford Bingham. The area was initially used for livestock and lumber…By the end of the century a boom in copper mining was taking shape at Bingham Canyon. Small mines were consolidated in the hands of large mining companies that had the resources to develop the mines on a scale not previously possible…The success of the local mines eventually proved to be the town’s undoing, however: by the mid-twentieth century the huge open-pit Bingham Canyon Mine began encroaching on the community. The last buildings were razed in 1972 and the expanding pit swallowed the entire town site…No trace of the former town remains today. Bingham is the largest mining city to be swallowed completely by an open-mine
Great Salt Lake Cutoff https://www.britannica.com/topic/Lucin-Cutoff Lucin Cutoff, portion of a Southern Pacific rail line built across the Great Salt Lake, Utah, in 1902–04, replacing a much longer part of the original transcontinental railroad that traced around the northern end of the lake. The cutoff bypassed steep grades, including those near Promontory (location of Golden Spike National Historic Site), and sharp curves on the original route between the cities of Ogden and Lucin (the latter city now abandoned). It included a railroad trestle across the lake connecting the two cities; the trestle was replaced in 1959 with an earthen causeway nearly 12 miles (19 km) long, which effectively divides the lake in two.

Tabernacle Organ and Choir https://history.churchofjesuschrist.org/story/museum/tabernacle-organ-exhibit?lang=eng The Tabernacle organ was first played during the October 1867 general conference of The Church of Jesus Christ of Latter-day Saints. In the 150 years that have followed, it has served as the iconic backdrop for meetings and events broadcast throughout the world. This famed instrument has influenced Latter-day Saint music, culture, and worship. Verbiage on the back of the postcard: “The ‘Mormon’ Tabernacle Choir is a volunteer, unpaid organization with a membership of 325. It is famous for its long, continuous service in the ‘Mormon’ church, its many years of national weekly radio broadcasts and its frequent concert tours.
The Great Organ of national renown was originally built in 1867 by Utah artisans. It has been thoroughly rebuilt and enlarged from time to time until it stands today the peer of, if not superior to, any pipe organ in existence.” [This postcard was mailed in 1939 from Salt Lake City]
