A British photographer has captured life at the “edge of the world”. Timothy Allen, best known for his work on BBC's Human Planet, trekked through the freezing Siberian wilderness for 16 days as he joined part of an 800km migration of reindeer in the Yamal-Nenets region – a name that roughly translates to “edge of the world”. The stunning pictures feature the nomadic Nenets tribe, who drink blood to survive in -45°C temperatures. Timothy's epic journey, which will be revealed in an eight-minute documentary on Animal Planet USA, saw him travel across the bleak terrain of the frozen Ob River with the Nenets people in December last year. Here: An empty camp is shown beneath a colourful sky in Siberia, December 2016. (Photo by Timothy Allen/Barcroft Productions)

These stunning images reveal the remains of a more than century-old sunken ship that has been preserved beneath freezing Lake Superior. The ship looks almost exactly the same as it did the day it sunk beneath waves all those years ago. At 60 meters long (approximately 198 feet), the «Gunilda» sunk after it struck some rocks and was not saved. Now, these stunning images have been captured 107 years after the sinking when a small group of divers revisited the vessel. (Photo by Becky Kagan Schott/Caters News Agency)
