Skyline Arch, Natural arch in Grand County, Utah, US
Skyline Arch is a natural sandstone arch in Arches National Park, Utah, positioned high on a rock wall in the Devils Garden area. The opening in the stone frames the sky behind it and is large enough to be seen clearly from the road nearby.
The arch formed over thousands of years through the slow erosion of sandstone. In 1940, a large boulder broke away from the upper part of the formation, making the opening considerably larger than it had been before.
The arch sits in an area of Arches National Park named Devils Garden, and it is clearly visible from the main road. Many visitors stop here on their way to other parts of the park, often to take photos or simply to look at the rock formation from a distance.
The trail to the arch is short and manageable for most visitors, though the ground can be uneven in places and sturdy shoes are a good idea. Getting closer to the arch itself requires stepping over rocks, so some care is needed on that last stretch.
The chunks of rock that broke off in the 1940 collapse are still lying at the base of the arch and are easy to spot. They are a visible reminder that the formation changed in a single moment after centuries of slow erosion.
