- Description:
- Navigational chart entitled, "Map of the Delta of the St. Clair [River]," that was compiled by Lieutenants J. N. Macomb and W. H. Warner "under the direction of Captain W. G. Williams, U. S. Corps of Topl. Engrs. [Topographical Engineers]." The survey work is dated 1842. The chart is drawn at a scale of 1:15,840 (four inches = 1 mile) and shows the area at the outlets of the North, Middle, and South Channels of the St. Clair River which flow into Lake St. Clair. The chart is drawn in black ink on slightly yellowed paper and shows shorelines, water depths in feet, marsh areas, navigational channels, a north arrow and magnetic north, and survey triangulation points. A small inset map in the upper left corner shows Lake St. Clair, the lower St. Clair River, and the upper Detroit River.
