Hoodoos -- Drumheller, AB -- May 25, 2009

Just to the east of Drumheller are the Hoodoos, geological structures that look like pillars with "hats". These formations are common in badlands areas, and are built when harder sediment exists on top of softer material. Over time the softer material erodes away, but the "pillar" is protected by the "cap" of the harder sediment. Over time the hoodoos will also erode away.

Smaller hoodoos, or "hoodoo rocks"

The area immediately around the area looks pretty cool too:

These are not small structures!! (And many around the world are much bigger)


These hoodoos are iconic enough they've been used in a number of videos, including Tom Cochrane's Life is a Highway

They are Nature's own pillars, though they hold up nothing more than the air. That was an interesting explanation of how they were made.
