The sites in the district include several places where flint was quarried.[4] They are all located along the shore of Lake Michigan, with the Pewangoning Quarry farthest south, Whiskey Creek slightly north, and Fritz Trail about a kilometer farther.[5]
^The NRIS lists the Pewangoning Quarry as "Address Restricted." However, references James Vol Hartwell (May 29, 2010), "Pi-wan-go-ning Arrowhead Quarry", Petoskey News place it just North of Norwood, near Whiskey Creek. Geo-coordinates are approximate.
