Provo • As Steve Acerson perused ancient petroglyphs on the west side of Utah Lake on an unseasonably warm February morning, he started getting more and more upset.
The rock art enthusiast and president of the Utah Rock Art Research Association goes out frequently to identify rock art, and is intimately familiar with many of the known petroglyphs in Utah County — he helped discover many of them.
But as he reached down to point out a petroglyph depicting a bighorn sheep, he noticed the top half of the sheep had been damaged to the point that anyone who wanted to could pick up the detached piece of rock depicting the sheep's head, put it in their pocket, and walk away.
