Yes, here’s another waterless “Water Work.” When it’s not waterless, that water works well. Spanning 180 feet, this large natural arch is composed of a tube of especially resistant Permian Cedar Mesa sandstone in Natural Bridges National Monument. Freeze-thaw cycles happen throughout the cool season when water in wet rock freezes to crystals, which expands and pries the grains apart from their cement, slowly weakening the stone until it cannot support its own weight. This already has happened for the rock that used to fill in the gap between the low ground below and the arch’s underside, and eventually will take down this and other natural bridges in the area, as well as shorter arches farther northeast in Arches National Park.
