The photographer and film-maker Timothy Allen (winner in 2013 of the Travel Photographer of the Year competition) has been making regular trips in recent years to Mongolia, where he runs photographic expeditions. He is due to release shortly his latest film, made with Thom Cytry. The Circle, which will be free to watch on YouTube, tells how the pair of them, helped by a group of Mongolian friends, tried to carve out a virgin route across the Altai Mountains to climb Mongolia’s tallest peak.
