Petroglyphs

Petroglyphs (also called rock engravings) are pictogram and logogram images created by removing part of a rock surface by incising, pecking, carving, and abrading.

 

Went out a little early this a.m. and finally found where these just west of Tucson. We'd gone looking for them once before, but did not have any luck. John missed them this trip, but I'll take him to them, now. These were done by Native Americans many, many moons ago.
