The 24,000-Year-Old Bones Found In A Yukon Cave — And The Cut Marks That Pushed Humans In North America Farther Back In Time
Bluefish Caves does not exist in archaeological isolation.
It is situated within a broader region — the Old Crow basin of the northern Yukon — that has produced one of the richest Late Pleistocene fossil records in North America and that has been the subject of archaeological investigation for more than half a century.
The Old Crow Flats, a shallow lake basin north of Bluefish Caves, is one of the most prolific sources of Pleistocene megafauna fossils in the Western Hemisphere.
The rivers that drain into and through the Old Crow Flats have eroded the permafrost-preserved sediments of the basin, exposing millions of bones of Ice Age animals.
