One of the valley's most important cultural sites is under assault by unknown vandals. The place is known as Little Red Rocks and it's home to petroglyphs that date back thousands of years.

Unlike most cultural sites, this one is on private property. The owner has spent a bundle to protect the area but nothing seems to work. Now a new partnership has been formed that is designed to protect what's left.

"At one point we put boulders across Charleston, I mean big boulders, and it took heavy equipment to set them. That wall was breeched in a couple of weeks. And we know that whoever did that had to use heavy equipment," said Howard Hughes executive Tom Warden who says his company has spent more than $1 million dollars trying to protect Little Red Rocks from vandals. Nothing works.
