Three small caves in the Old Crow Basin of the northern Yukon, possibly the earliest evidence of occupation in North America so far recovered. Discovered in 1975, and subsequently investigated by Jacques Cinq‐Mars, the earliest layers at Bluefish Cave I yielded a few flint chips indicative of human activity in association with broken animal bones from Ice Age mammals such as the horse, bison, and caribou. The deposits are thought to date to between 15 000 and 12 000 bc.
