Abstract

To the south of what is now Canada, French military expeditions explored and mapped the Ohio River valley in the period 1739 to 1749. These expeditions were led by Le Moyne and Céleron (1739) and Céleron and Bonnécamps (1749). The map also shows the extent of territory known to Europeans and the navigation of all exploration routes in the period 1651 to 1760. The historical names found on the map are derived from contemporaneous maps and written documents of the period.
