DEL NORTE – The Bureau of Land Management is investigating a case of vandalism at one of its sites in Del Norte. Teenagers allegedly scraped their initials on to the side of a cliff where prehistoric art is preserved.

"It's appalling," said Michael Troyer, an archaeologist with the Bureau of Land Management.

"Anytime we see vandalism on public lands, archaeology resources such as these are legacy to all Americans," added Kyle Sullivan, who also works for the BLM.

Sullivan says his agency believes some punk kids likely hiked up to the site, put their initials in the petroglyph and thought it was cool.

"This is someone else's heritage enshrined in the rock," Troyer said.

Kids sure can do some damage, but they can also do some pretty amazing things.

In an effort to turn a bad situation in to a good one, the BLM enlisted the help of students from Sunshine Christian School in Alamosa.

The kids learned about art, history and graffiti. They also learned how graffiti can destroy things.

"We want them to know these resources belong to them," said Sullivan.

With the help of the BLM, the students learned how to repair the damage done by the graffiti artists.

They filed down the markings, smoothed them out and made them pretty much disappear.

"Kids are the next generation of land managers," Troyer said.
