Early Probes of the North Pacific Coast 1741

In 1741, along the Pacific coast, the first Russian probes reached the Aleutian Islands and the Alaskan mainland. These were the expeditions of Bering (1741) and Chirikov (1741). 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.
