[demont]

I found this rock in my back yard when we dug up the ground to put a pool in. Can anyone identify it? Its about 4 to 4 1/2 inches long close to 3 inches wide.

Looks like an ordinary river stone.

99.9% sure that is just a river bed rock.

Its a kidney stone!!

Any other rocks coming out of the hole, or is that one unique? It's looks to be a river cobble, and if there are no other rocks of that type in the area, then it was packed in. It resembles something stone age people might have used, but it's also so common it's hard to tell, which is why I ask if it is unique to the location it was found.

I found alot of other odd rocks in the dirt pile when I found that rock but none of them looked like the one above. I know nothing about rocks but these were some of the more unusual ones to me.

Folks around here call them 'biscuit' rocks, but it is like others have said, it's a river rock. Breezie

River rocks are often used in landscaping.
