For those interested in North American prehistory

Obsidian flakes found at the bottom of Lake Huron at a location that apparently was a land bridge across the lake 9,000 years ago.  More about the topography of Lake Huron.

Interesting because this obsidian was obviously crafted by humans, and it was not locally sourced.  It would have come from the area that is now the state of Oregon.


  1. I've always found the prehistoric eras of North America very fascinating. People are just so clever, always have been. Quite interesting video. Thank you TYWKIWDBI.

  2. Thank you. I am impressed by blades found at Ground Hog Bay in Alaska, 200 miles.norh of source
