In 1648 Semyon Dezhnyov sailed from the Kolyma River past Cape Dezhnev and through the Bering Strait, eighty years before Vitus Bering entered the strait in 1728, and ended up wrecked near the mouth of the Anadyr.
The route follows the voyage from Srednekolymsk to the cape, the Diomede Islands, the Anadyr mouth and the winter quarters at Anadyrsk. Some details, including the exact route, are debated, so most pins are approximate.
Vitus Bering's Kamchatka expeditions went from Saint Petersburg through Tobolsk and Okhotsk to the Bering Strait and Bering Island. In 1725 the Russian naval captain set out across a continent to find out whether Asia and America were joined.
The route follows seven places from the Tsar's order in Saint Petersburg to Bering's death on an uninhabited island in 1741. The stops are not one continuous line, so they are shown as separate markers. Dates are Old Style (Julian), as Russian records of the time kept them; the modern calendar runs 11 days ahead.
