[Rockhounds] Obsidian in Michigan

[Kreigh Tomaszewski]

Obsidian has been found in Michigan, brought in by Native American's ~9,000
years ago from Oregon.

I live in Lower Michigan, and if you go out in my yard you can find
obsidian.

Obsidian can be found in lower Michigan, but it was imported from somewhere
else (or possibly dropped here by a glacier).
