The Hoodoos
A hoodoo is a tall thin rock spire made of sandstone with a hard and dense rock sitting on top, like a hat. Or as the sign at the park describes them: “Eroded pillars of soft sandstone rock topped with a resilient cap.“
The hoodoos are formed over hundreds of years through erosion from freezing, frost, melt and wind. Over time, the sandstone erodes into long chimney-like formations that remain standing because the hard rock “hat” keeps it from completely eroding away.
The hard rock on the top of the hoodoos protects the soft layer of sandstone underneath from the elements creating the odd shape. But once they reach the stage of being the cute fairytale chimneys, they don’t last long! It is said that every 100 years, they lose 2-4 feet.
