Drones are not only used to kill people! This video claims “Drone discovers ancient petroglyphs in Utah!”

The following video was made by Bill Clary from Colorado. According to him, the petroglyphs were filmed on a high canyon wall in Southern Utah. He declined to say exactly where.
Archeologist at the Colorado Plateau Archeological Alliance, Jerry Spangler believes it is possible that the petroglyphs seen in the video have gone unnoticed for centuries. He describes them as what they call San Juan basketmaker style, a very classic style made by the basketmaker people from about 500 B.C. through around 8600.
Here the interview with the archeologist from Fox13 News:
Well go for it and buy a drone! According to him, there are plenty of still uncovered archeological sites in Utah. Of course it is illegal to tamper with, vandalize, or remove anything from an archeological site on public property.
It seems that drones could become an invaluable research tool!
