Colorado Backyard Yields Cache of Stone Age Tools





Researchers into the ancient human past are used to wandering the world in search of artifacts. But scientists at the University of Colorado said Wednesday that a major cache of Stone Age tools, believed to be 13,000 years old, had been found in a suburban backyard just six blocks from the campus in Boulder.

“I’m used to going hell and gone across the landscape to look,” said Douglas Bamforth, a professor of anthropology who analyzed the cache. “This time I walked.”

The 83 stone-cutting implements, some with enough blood residue on them to identify the animals they had been used to butcher, are believed to have belonged to a nomadic people who probably buried the tools for later retrieval, but never returned, Professor Bamforth said.
