Hmmmm. I thought the Great Lakes were carved out by a glacier during the last ice age? If so, how does a human built circle of stones manage to either wind up on the bottom of a lake, or magically become moved & deposited there by the retreating glacier? Doesn't seem to make much sense. Maybe it's near the edge, which used to be above water after the lake was originally formed?

That’s my problem with it to. It’s also not about how long ot took to build them but the ammount of time it would take for a civilization to begin to see a place as sacred.

I no longer believe the Great Lakes were carved out by a glacier during the last ice age. That makes no sense when viewing the bathymetric maps of the regions.
