Photograph by @paulnicklen // Into the polar bear’s lair. Tracks from a large polar bear lead off into a glacial cave along the coast of Svalbard, Norway. If there was a bear in that cave or not, I was happy to leave him/her in peace. #followme on @paulnicklen as I celebrate polar bears all week. #mysteriesofthenorth #thejourney #bear #polarbear #tbt #instagood
