No doubt the surf that finished the arch was but one of thousands over a long and inevitable period of erosion. Time and the natural elements ALWAYS keep changing the landscapes of the earth - non stop.
Folks. I went to college at SLO. I went to Montana de Oro often. It was peaceful and beautiful. The fact that this landmark has fallen simply saddens me. However...it was created by nature in the first place. I am just glad that I got to enjoy it.
