Mesa Arizona it's funny because the only one that you guys really commented on was the one I scrubbed all the dirt off a wire brush I just don't want to do it that anymore because I don't want to wipe off any DNA.

I am uncertain about this one, however it does trigger quite a few well known glyphs in simple head profile form and a crude cloaked figure.

The first pic also triggers for the thumb motif left and bear head right, although subtle, and too the right appears to be deliberate modification in the form of three parallel flake removals.

Nice stones!

I use an old toothbrush to clean the stones asa've found a wire brush has marked the stones in the past.

Saying that, some of the stones are best viewed after cleaning and leaving them outside for a couple of weeks placed on the Earth.
