Victor, the good stuff was collected by the state ages ago. DB had the ranger's permission (you have to pass a ranger station to get on to this preserve). These rocks are only found intertidally, in the winter, when the clay substrate is exposed. There were arrowheads there, once.
ONLY my DB would be standing in mud on a North-facing barrier beach in January. Except, I confess I bird-watch there in February!
Add to the fact that they look like plain 'ol beach stones to me!
A grinding tool?:
