Description
This uncommon collection of maps, diagrams, and tables of statistics was compiled under the authority of the Geological Survey of Michigan between 1869 – 1873. Legislation was passed shortly after the Civil War to resume earlier geological mapping efforts, resulting in the state’s third survey that continues to be ongoing today.
The contents focus on the economic potential of Michigan’s Upper Peninsula. At the time, the remote area was producing the vast majority (nearly 90%) of the nation’s copper and enjoyed large deposits of iron and nickel. The results of geological surveys such as this were instrumental in encouraging further financial investment, developing railroad infrastructure, and tempting additional settlement.
