A color postcard looking over Bisbee to the Northwest, circa 1950s.

The message on the back in ink reads: “Dear Sis, Jack & I just returned from a trip to Bisbee. Wanted to write you from there but didn't have your address. We enjoyed our trip so much. Jack found Bisbee greatly changed We also saw Hank at Tucson & spent a few days with Peggy & family. Belle drove as far as San Diego with us. Hope you enjoyed your vacation as much as we did. All our love, Ree & Jack”. The postcard was published by Lollesgard Specialty Company and was sent with a red two cent Thomas Jefferson stamp. Willis, Minnie Collection

The Lavender Pit was named after Phelps Dodge vice president and general manager Harrison M. Lavender. Work in the pit began in 1951, and it was dedicated on 1954. Phelps Dodge invested $25,000,000 ($260,548,076.92 in 2021) in developing the Lavender with the hope that it would produce 38,000 tons on copper on a yearly basis by 1955. Among the buildings that were relocated during the expansion, was the office building of the Shattuck and Denn Mining Company. Moving the 300-ton brick structure was done with great care and at a snails pace, moving a single foot every ten minutes. The office was the last structure moved, and it’s new home lay 3,000 feet from its original location. The moving company’s owner, R.C. Burke, noted that though if not the largest building that he ever moved but it was the most difficult job due to Bisbee’s hilly terrain. In the move, one hundred homes were transferred from the Johnson Addition and other areas to Saginaw. In total, 250 homes and business had to make way for the expanding pit. In January 1959, Walter C. Lawson announced that the 155 acre, 300 feet deep pit would receive a $5,000,000 dollar expansion. In comparison to the Sacramento Pit, the Lavender used electric powered shovels which were four times larger than the old steam powered ones. The rail track based ore cars were replaced by trucks with a capacity from 35 and 65 tons. After twenty four years, mining in the Lavender Pit came to an end in 1975. In October 1977, George Nellis, a security guard at the Duval Pit Mine in Tucson, made the proposal of utilizing the Lavender Pit to build a terraced retirement community housing 100,000 people. Though the idea never came to fruition, retirees were a factor in sustaining Bisbee after the end of mining. The Lavender Pit remains a stark reminder of industrial might of mining companies to permanently alter a natural landscape. At the end, the Pit reached a size of covering 300 acres and reached the depth of 900 feet, ten times larger then the former Sacramento Pit. In the hunt for copper, 351 million tons of rock removed, producing 600,000 tons of copper.
