The photo above shows the heavily sculpted and twisted Antelope Canyon, near Page, Arizona. Upper Antelope Canyon (shown here) is approximately 1/4 mile (0.4 km) long, about 130 feet (40 m) deep and, in places, less than a few feet wide. It's reached by hiking along a 3 1/2 mile (5.6 km) sandy wash. This is one of the many slot canyons in the high desert of northern Arizona, which were formed by deposition of sandstone and later cut by the power of rapidly moving water. This process continues today and has claimed the lives of those who explore the narrow slots without heeding nearby thunderstorms that often result in flash flooding. In August of 1997, such a flood killed 11 people caught inside the deep and narrow Lower Antelope Canyon.
