This is a famous arch in Canyonland NP, Utah called Mesa Arch. I must admit that I had never heard of it before we went to Moab, Utah and I saw it. However, not long after returning home from the trip, I saw a poster in the local coffee shop with a picture that included the arch and I immediately recognized it. Since then, I have seen it a number of times.
I’m sure that we have all had the experience of “seeing” something without really noticing it. Maybe that something is actually a someone. It is often said “the more you know, the more you know you don’t know.” I think it could also be said that “the more you see, the more you realize how little you see.”
