Description

This sheet shows an interesting side view of Copper Falls mine, near Eagle Harbor in Keweenaw County, Michigan. Three separate levels are connected by a vertical shaft at least 150 feet deep, with profitable ore found in the trap between layers of sandstone. According to Michigan Tech;

“The Copper Falls Mine was established near Owls Creek in Keweenaw County in the 1840s at the site of a prehistoric mining pit. The mine operated for over 40 years and produced, according to a Daily Mining Gazette article from 1956, “12,843 tons of ingot copper,” and employed “mostly Cornish, Finnish, and Irish” workers until its closure in 1901.”

Surveyed by J. Child in 1848 and published by the Government Printing Office in 1849 as part of the Annual Message and Accompanying Documents to Congress. Lithography by Ackerman in New York.
