A group of hikers high-fived after one of them intentionally pushed over a large rock, which is part of the "goblins" or "hoodoos" formation, and is nearly 200 million years old.
The men filmed one of their buddies referred to as "Glenn" pushing the giant rock from behind (video below).
According to The Salt Lake TribuneYouTube page, "Three men, tagged as Dave Hall, Glenn Taylor and Dylan Taylor, push over large rock boulders in Goblin Valley, Utah in this video posted to Hall's Facebook page."
After the rock comes tumbling down, the men celebrate their accomplishment in Goblin Valley State Park in Green River, Utah.
"We have now modified Goblin Valley," says the man filming. "A new Goblin Valley exists with, uh, this boulder down here on the bottom. Muscles here pushed it off."
At one point the cameraman states, "That's crazy, it was just held up by this little piece of dirt."
Now, the three men may be facing felony charges and could end up high-fiving in jail.
"It is not only wrong, but there will be consequences," Utah State Parks spokesman Eugene Swalberg told The Salt Lake Tribune. "This is highly, highly inappropriate. This is not what you do at state parks. It’s disturbing and upsetting."
According to DailyKos.com:
The unusual shapes in Goblin Valley result from a weathering process of Entrada Sandstone (a principal formation in the San Rafael Group). The formations have large orange-brown boulders of rock placed on top of weaker sandy layers, which have thus eroded more quickly (the process of differential erosion). The Entrada sediment was deposited during the Jurassic period of the Mesozoic Era (180 to 140 million years ago).
