Most of our visit was under grey dismal skies, not photo friendly. Occasionally the heavens opened up and I was able to take advantage of the light.
Landscape Arch at 290 feet across is the longest span in the park. Several years ago a slab broke free from underneath and since then then trail that led beneath the arch has been closed. Considering some of the other trails I was on, having some rock fall down on me would be the least of my concerns.
