Archaeologists in the northern Minnesota town of Walker dug up the items, which appear to be beveled scrapers, choppers, a crude knife and several flakes that could have been used for cutting, said Colleen Wells, field director for the Leech Lake Heritage Sites Program.
"They don't look like much," Wells acknowledged. "They don't look pretty."
No pictures and not much else to go on. The key seems to be the artifactual nature of the objects and the dating.
