Flashback Friday to a view of the stamp heads at Cliff Mine in Keweenaw County, 1926.
Owned and operated by the Pittsburgh & Boston Mining Company, the Cliff Mine was established in 1845 and quickly became the first profitable copper mine in the region. By 1849 the mine had paid out its first dividend and grew to become one of the most successful mines in the region during the mid 1800s. Cliff Mine operated consistently until 1854, but by the early 1870s the mine was in a financial decline and was sold. The land at Cliff was eventually taken over by the Calumet and Hecla Mining Company, but by the early 1900s all mining interests in that region were abandoned for more profitable pursuits.
