On 18 June 1937 three Soviet airmen took off from Moscow in a single-engine plane and landed in Washington State more than 63 hours later, having flown over the North Pole. It was the first non-stop flight from the Soviet Union to the United States.
The route follows the crew from the airfield near Shchyolkovo to the landing at Pearson Field, then to the general's table, the White House and the monument that still stands by the runway. The path over the Arctic is shown only as a symbolic pin.
A Russian student expelled from university in 1864 ends up living among people in north-eastern New Guinea who had never seen a European. Nikolai Miklouho-Maclay was a zoologist and anthropologist, an early follower of Darwin who refuted the view that human races were different species.
The route follows him from Haeckel's Jena and the Canary Islands to Astrolabe Bay, the Sydney research station he founded, and his grave in St Petersburg. Most pins are approximate: the sources name regions, not camps.
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.
Disguised as a beggar, a Belgian-French explorer walked into the forbidden city of Lhasa among pilgrims. Alexandra David-Néel and her adopted son Yongden stayed two months in 1924, then slipped away before the governor could act.
The route follows her from Kumbum, where she studied for years, across the Kyi to the Potala and the Monlam crowds, then on to Samye, Tsetang and Gyantse. Pins are area-level, and critics have disputed her account since 1972.
Nikolay Przhevalsky made one expedition to the Ussuri region and four to Central Asia, crossing the Gobi, reaching the wandering lake of Lop Nur and getting within 260 km of Lhasa. He died at Karakol on Lake Issyk-Kul, on the eve of a fifth journey.
This route follows six stops from those journeys and his years between them. They were separate expeditions rather than one trip, so the markers are not joined. Dates are years only.
On 10 November 1871, on the shore of Lake Tanganyika, the journalist Henry M. Stanley took off his hat in front of a crowd and said, as he tells it in his own book, "Dr. Livingstone, I presume?" The explorer many thought dead had been found, after nearly eight months on the road from the coast.
The route follows Stanley's account, How I Found Livingstone, over eight stops: from Zanzibar and Bagamoyo through Mpwapwa, Tabora and the Malagarasi to Ujiji, then up the lake to Mugere and back to the parting at Tabora. Stanley's camps are rarely identifiable today, so every pin is approximate.
A young bear stows away from Peru, turns up at Paddington station and is taken in by the Brown family. Paul King's 2014 film follows him through a cosy London of antique shops and a gentlemen's club, while a taxidermist closes in.
Most of it was shot on real London streets. This route runs from the station to Primrose Hill, Portobello Road, Pall Mall and the Natural History Museum, with one caveat: the film's station front door is borrowed from Marylebone.
