The Wave (Coyote Buttes North)

The Wave is perhaps the most heavily photographed and tightly regulated natural attraction in the American Southwest. Situated in the Coyote Buttes North Special Management Area of the Paria Canyon-Vermilion Cliffs Wilderness, it is a magnificent, surreal basin of swirling, intersecting U-shaped troughs of Navajo sandstone. The rock is fiercely striated with vivid red, orange, yellow, and white banding, formed by Jurassic-era sand dunes compacted over millions of years and then eroded by wind and water. Because the landscape is incredibly fragile, access is strictly limited by the Bureau of Land Management (BLM) to a tiny number of lucky lottery winners per day. There is no marked trail; hikers receive a pictorial map and GPS coordinates to cross wild, trackless slickrock and deep sand to locate the formation.

Following the historic path used by the Army of the Andes in 1817, this 6-day trans-Andean expedition traverses the central cordillera from Mendoza, Argentina, to the Cajón del Maipo in Chile. The route crosses two significant high-altitude barriers—Portillo Argentino (4,330m) and Paso Piuquenes (4,030m). Hikers move through a high desert landscape of volcanic rock, vast glacial valleys, and the powerful Tunuyán River. The terrain consists primarily of rocky mountain paths, loose scree on the steeper pass approaches, and high-altitude plateaus where exposure to wind and sun is constant.
