The Hoodoos

Hoodoos are sandstone pillars that can be found throughout the badlands.

The name "Hoodoo" comes from the word "voodoo" and was given to these geological formations by the Europeans. In the Blackfoot and Cree traditions, however, the Hoodoos are believed to be petrified giants who come alive at night to hurl rocks at intruders.
