In the early 1900s a Russian army surveyor, Vladimir Arsenyev, mapped the wild Ussuri taiga with the help of Dersu Uzala, an indigenous hunter who read the forest better than any map. Arsenyev's memoir became a classic, and Akira Kurosawa turned it into an Oscar-winning film in 1975.
The route follows the story from Vladivostok to Lake Khanka and the Sikhote-Alin, then to Khabarovsk, Dersu's lost grave and the film's shooting base. Pins mark regions and towns, not exact campsites.
In 1725 a Russian naval captain set out across a continent to answer one question: are Asia and America joined? Vitus Bering's two Kamchatka expeditions, the second of them part of the Great Northern Expedition, took years of hardship to answer it.
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.
On 12 April 1961 a pilot climbed into a small capsule on top of a rocket and became the first person in space. The flight lasted less than two hours; the road to it took a year of training, and the days after it turned a pilot into a worldwide celebrity.
This route follows Yuri Gagarin from the training ground at Moscow's Khodynka Airfield to the launch pad at Baikonur, the field in the Saratov region where he came down, the Kremlin ceremony and the museum that keeps his capsule. The museum pin marks the Energia company site rather than the museum itself.
In the spring of 1890 the playwright and doctor Anton Chekhov left Moscow, crossed Siberia and sailed to Sakhalin, a convict island north of Japan, to count its inhabitants one by one. He kept the plan secret until January, travelled 82 days across Siberia, and came home months later by sea.
The route follows his way from his Moscow house through Tomsk, Irkutsk and the Amur to the penal posts of Sakhalin and back to Vladivostok. Several pins mark whole towns, because Chekhov's lodgings are not recorded.
