Colton’s Lake Superior and the Northern Part of Michigan

Colton’s double sided atlas map featuring the upper and lower peninsulas of Michigan.

This detailed map was originally issued by Joseph Hutchins Colton in 1855 and has been updated to the late 1860’s in a later publication by his successors, G.W. & C.B. Colton. It shows the surveyed status of Michigan’s upper peninsula, organized into eight large counties, plus Isle Royale in Lake Superior.

The few railroad lines serving the region are shown, as are a number of prominent geographic features, settlements, townships, forts and boundary lines. Prominent local industries, such as copper, fur, and iron are also labeled accordingly. The verso features a similar map of Michigan’s lower peninsula.
