Red Rock Canyon, Whiting Ranch Wilderness Park, California

The red fruit of this cactus can be eaten. You should, however, burn off the spines (and there are a lot of them) before picking the fruit.

As the wind enters the canyon from the north it gets compressed and accelerates. The resulting flow is powerful enough to wear down the rock, creating this smooth, buckled surface.
