A reindeer herd browses near a Koryak camp in northern Kamchatka. The reindeer are semi-domesticated, and a couple of Koryaks can keep the herd under control with whistles and gestures. They do the work of cowboys, but all from on foot. The small camp that shadows the herd usually consists of two or three related families with their tents and a few horses, which shoulder the heavier gear when their owners must move camp. The Koryaks get their food, clothing, tent materials, and most everything else they need from the reindeer. This symbiotic relationship has been going on largely unchanged for thousands of years. Note the yearling with just-developing antlers standing in front of the white reindeer in this photo.
