In today’s photo we’re looking at some reindeer, known as caribou here in the US state of Alaska, crossing the Susitna River. Alaska has 32 distinct caribou herds. It’s likely the caribou in today’s image are members of the Nelchina herd, which roams across about 50,000 square kilometres in the high basin surrounded by the Talkeetna, Chugach, Wrangell and Alaska ranges.
