Hoodoo You Do

Hoodoos. Fairy chimneys. Earth pyramids. Tent rocks. They have many different names, but these strange badland rock formations are one and the same.

"These strange geological wonders are formed over many centuries through a combination of physical and chemical weathering forces. This includes erosion through wind and acid rain, but the most powerful process that helps sculpt these formations is frost wedging.

As the National Park Service explains, 'in the winter, melting snow, in the form of water, seeps into the cracks and freezes at night. When water freezes it expands by almost 10 percent, bit by bit prying open cracks, making them ever wider, in the same way a pothole forms in a paved road.'" (Mother Nature Network)
