what do y'all think these are..
they are in a big rock in front of a rock shelter/overhang. To me they look modern made, but I don't know why or with what. The shelter is in a old, very active oilfield, but it is over a bluff, in some very rough terrain, can't imagine any drilling equipment taken down there to just make a few marks in the stone...anyway, ideas?
