Wyoming Hoodoos

Photo Friday Challenge: Transmogrify

Today’s Photo Friday Challenge is “Transmogrify,” which means “to change in appearance or form, especially strangely or grotesquely; transform.” Rocks known as hoodoos are a prime example of transmogrification. What is a hoodoo? In geology, it’s a column of rock that is weathered by the elements (rain, wind, etc.) into a usually top-heavy form.

These hoodoos from the Wind River Basin in the US state of Wyoming are made of sandstone, and thus they have a soft look about them. You can see them throughout the northwest US and into Canada. The same structures appear throughout the world, and there some spectacular examples in places like Taiwan and New Zealand, which I unfortunately have been unable to visit.

Hoodoos form where rock that resists weathering lays on top of softer, more easily weathered rock. The softer rock weathers away faster, and the more resistant rock rests precariously on top. Sometimes it’s the same rock, like these sandstone hoodoos, and in other cases the two rocks are of different types. Usually, hoodoos are found in national parks and other desolate areas (like the ones I found in Wyoming), so you might have to hike to find them.

Have you ever seen a hoodoo? What is your favorite geology feature? Hot springs? Volcanoes? Let me know in the comments!
