Description
This interesting multi-part sheet shows a detailed overview of the Northwest Mines in Keweenaw County, part of Michigan’s Upper Peninsula. The region was a valuable source of copper for indigenous people for thousands of years, and in the late 1840s the first profitable mechanized mining ventures began to open. The image shows sectional views of three important copper ore veins, as well as an overview of the small mining community.
Surveyed by S.W. Hill in 1847 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.
