Underwater archaeology team finds ancient obsidian flakes 2,000 miles from quarry

 



“An underwater archaeologist from The University of Texas at Arlington is part of a research team studying 9,000-year-old stone tool artifacts discovered in Lake Huron that originated from an obsidian quarry more than 2,000 miles away in central Oregon.

The obsidian flakes from the underwater archaeological site represent the oldest and farthest east confirmed specimens of western obsidian ever found in the continental United States.

 “In this case, these tiny obsidian artifacts reveal social connections across North America 9,000 years ago,” said Ashley Lemke, assistant professor of sociology and anthropology at UT Arlington. “The artifacts found below the Great Lakes come from a geological source in Oregon, 4,000 kilometers away—making it one of the longest distances recorded for obsidian artifacts anywhere in the world.”

The find in Lake Huron is part of a broader study to understand the social and economic organization of caribou hunters at the end of the last ice age. Water levels were much lower then; scientists have found, for example, ancient sites like stone walls and hunting blinds that are now 100 feet underwater.


“This particular find is really exciting because it shows how important underwater archaeology is,” Lemke said. “The preservation of ancient underwater sites is unparalleled on land, and these places have given us a great opportunity to learn more about past peoples.”

Falmouth area arrowheads - ID requested

 Can any one identify the arrowheads here:

I am particularly interested in this one, which looks like a late stage "paleo" point:
Note the base is "thinned" compared to the upper part.
Wow. Wish I found it.

Clovis First Dies (AGAIN!)

New evidence may change timeline for when people first arrived in North America (phys.org)


[Research from 20 or so years ago at Monte Verde in Chile already changed that "timeline". Seems like the only people still promoting a 13K time depth for man in America are textbook writers and YouTube.]
