Depicts hoodoos near Drumhelter, a town within the Red Deer River valley in the badlands of east-central Alberta, Canada.

Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water.

A hoodoo (also called a tent rock, fairy chimney or earth pyramid) is a tall, thin spire of rock that protrudes from the bottom of an arid drainage basin or badland. The hoodoos in Drumheller, Alberta are composed of clay and sand deposited between 70 and 75 million years ago during the Cretaceous Period. These hoodoos are able to maintain a unique mushroom-like appearance as the underlying base erodes at a faster rate compared to the capstones, a rate of nearly one centimeter per year, faster than most geologic structures.
