Polar frame, by Dmitry Kokh, Russia. When Kokh’s boat approached the small island of Kolyuchin in the Russian High Arctic, which had been abandoned by humans since 1992, he was surprised to spot movement in one of the houses. Binoculars revealed polar bears – more than 20 in total – exploring the ghost town. Dmitry used a low-noise drone to document them. (Photo by Dmitry Kokh/Wildlife Photographer of the Year 2022)
