At this unique formation, Navajo sandstone in shades of deep red to white was first eroded by water and then primarily by wind to create smooth, rolling terrain that resembles ocean waves. The differing densities of stone have caused the structure to erode at varying speeds, resulting in undulating fins of rock along the entire surface. Made up of two separate U-shaped troughs, the Wave is as narrow as seven feet, as wide as 60 feet, and more than 100 feet long. To preserve its serene nature, the Bureau of Land Management only issues 20 permits per day to visitors. If you’re lucky enough to secure one, you must then hike nearly three miles across the open desert from the trailhead closest to the site to reach it.
