Absolutely. Idiots indeed. I have some problems with some of the parks management but just destroying our resources is asinine.
There was a Walt Disney cartoon some years back ("Grand Canyonscope" 1954) about how Donald Duck unintentionally destroyed similar rock formations at a national park. He was beset upon by an irate and pudgy Park Ranger (J. Audubon Woodlore) who gave him a broom and instructions to make right all he'd destroyed and put it back in its original state.
Ranger Woodlore: Well, I hope you're satisfied. You two have, in a matter of minutes, messed up what it took Mother Nature millions of years to create. The National Park Rule Book states, and I quote, "When a natural object is marred or defaced, it must be restored to its original state." So, start digging!
