Boy Scout Leaders Destroy Ancient Rock Formation

A group of guys are in big trouble for destroying a national treasure.

They toppled a 200-million-year-old rock formation that dates back to Jurassic times and celebrated the destruction like they just won the lottery.

It happened in Utah’s Goblin Valley State Park, which boasts breathtaking landscape often compared to Mars. It's filled with thousands of rock formations that look like goblins. Some liken them to mushrooms.

They were formed by wind erosion and survived for millions of years—until these guys showed up. Believe it or not, they're Boy Scout leaders.

INSIDE EDITION caught up with Glenn Taylor and Dave Hall via Skype. They claim the rock was wobbly and could have fallen on someone.

Hall said, “We as scout masters, saw a very unstable situation that was only going to end up as an unsafe scenario if someone got up and jumped on it.

INSIDE EDITION's Paul Boyd asked, "What do you say to all those people calling you knuckleheads and doing what you did?"

Hall said, “Based on the video, I would agree with them 100%, but, if I was a parent and I knew there was a guy who knew there was a 2,000 pound boulder teetering over my kid and didn't do a darn anything about it, I would be furious."

One blogger calls it a "Moronic act."

One person wrote, "This really breaks my heart!" 

Another wrote, "How dare they ruin a national treasure."

Now, the State Parks Departments is investigating, toppling the goblin could land the men behind bars if they are charged and convicted.

It appears these guys may have forgotten rule three of the Boy Scout code: "Be considerate in the outdoors."
