Possible nutting stone...

Light swirl marks in the hole....a secondary hole is not as deep and right beside it.....very hard stone....thoughts. Found in an area with heavy Native American traffic here in Maine

There would be a difference in the patina between the depression and the rest of the rock. I don't see any pecking marks in the depression. Rocks with holes and depressions are pretty common. Gary

Please, as we see lots of things like this brought here, do yourself a favor and google up omarolluk and see for yourself.

The depression would likely show more polish than swirls if had been used.
