Authorities say three men could face felony charges after purposely knocking over an ancient Utah desert rock formation and posting a video of the incident online.

State parks spokesman Eugene Swalberg says the formation at Goblin Valley State Park is about 170 million years old. The park in central Utah is dotted with thousands of the eerie, mushroom shaped sandstone formations.

Glenn Taylor of Highland, Utah, says he knocked over the large boulder on top of the structure because it was loose and he thought it would fall and hurt someone.

Taylor says he wishes he could take back his actions but also says his conscience told him he did the right thing.


Swalberg says a county prosecutor and the state attorney general's office are investigating.
