Some maps documenting resurveys are also included. The maps show bodies of water and land formations throughout the state.

What's the story behind this collection?What’s the story behind this collection?

The initial survey of the State of Michigan was conducted primarily between 1815 and 1860. The federal government contracted land surveyors who earned between $3.00 and $4.25 per mile to pay their crews and cover supply costs. Crews usually conducted surveys in the winter because their line of sight was improved and they could walk across frozen lakes and ponds. Crews typically took about 20 days to survey a township with two surveyors, two axe men to trim brush, and two chain men.
