This is the Delicate Arch in Arches NP. It seems like an oxymoron to call this stone formation delicate. On the other hand, it seems certain that this arch will eventually crumble due to erosion from wind and rain.
It’s good to remember that everything in this world is delicate (passing away). We are called to “store up treasures in heaven, where neither moth nor decay destroys” (Matthew 6:20)
