5b.32 Obsidian Objects
The obsidian used by the Hopewell culture came from at least two sources: the Yellowstone region of Wyoming and Bear Gulch in Utah. The small number of Hopewell obsidian objects suggests that little of the material was brought to the Ohio Valley. Most of what was imported came to the Hopewell Mound Group in Ross County. From there it was traded throughout the Midwest as unworked chunks or finished pieces.
A cache of nearly 150 obsidian blades and points found in Mound 25 of the Hopewell Mound Group, as well as nearly 300 pounds of fragments and chips beneath Mound 11, show the importance of that site in obsidian trade.
