Dave if you dig here let me know if you are finding a lot of carved rocks small to medium.
Also, between your foot and the rock is a gray rock(small) that has white and black on it, then under the chin of the fish is a cresent moon, but when you look closer it looks like a mask, that's black on one side and white on the other, Follow the point of the moon to the left edge of pic. there is a gray rock that has more carvings on it. If you look all around you on the ground you will see carved rocks everywhere. That's what drives me crazy. VERY COOL FIND!!!!!!
