It is great that there is an antiguities act but it does little good without any enforcement. That has been the situation and continues to be the situation in much of the southwest, including the culturally rich areas around Blanding and the area that was designated as the Bears Ears Monument.
I am not saying we should ignore the issues, but the attention to this incident is just silly compared with the destruction that is happening on a massive scale.
BTW, unless something has changed recently, Corona Arch, is beautiful but it is not a "protected area". It is just another patch of BLM land like tens of thousands of other acres. There has been some attention because daredevils like to climb on top of the arch and then bungie jump or swing through the arch opening on ropes. I am not sure if that has been officially prohibited. If so, I have seen no signs of enforcement and when I have visited people were still swinging on ropes.
