Today’s post is a follow-up to our recent Monday: Map Day! – Wisconsin’s Federal Roads in 1840. It features another document created by the U.S. Army’s Corps of Topographical Engineers and preserved in the collections of the National Archives and Records Administration. Today’s drawing interests us as it documents—in some detail—the kind of road building work that Pvt. (later Sgt.) Jonathan M. Clark performed as a member of Company K, 5th Regiment, U.S. Infantry.
