Agreed.
Stand near the base, and it’s hard to really take it all in.
Look out from the top, and it becomes QUITE impressive.
Interesting story: Some years back, there was a moderate earthquake in nearby So. Illinois: People visiting the Arch for the 1st time thought the swaying of the structure was normal / just the wind. The employees who happened to be at the top at the time were the ones more worried.
That said, I believe the structure is thought to be fairly earthquake resistant.
I know...I drove by on a highway at night after I had been on the road for about 12 hours...I think I had seen the documentary on it years ago, and it made me think it was a lot bigger than it was.
