Hoodoos are a geological formation when erosion attacks a hard rock layer over a much softer rock. Some are small and others as tall as a 10-story building. Because of the minerals in the rock they can have spectacular colors. They are found all over the world, typically in dry, hot areas, and the most impressive are in Bryce Canyon National Park. If you want to know more about how they are formed, the National Park Service has a good explanation. As you can see in the photo below, as the mesa has eroded over the eons, freeze/thaw cycles and erosion has removed the rock, leaving spires of varying height – as if they were dug from the ground.
North from the entrance to the National Park you will find the trailhead to Mossy Cave and Tropic Ditch. In 1892 pioneer setllers of the town of Tropic worked for over two years digging a canal to divert water from the Sevier River, over the cliffs of Bryce Canyon and into the Tropic valley, a distance of 15 miles and a drop of 1,500 feet. To reduce the labor, they followed natural courses where possible. Except for the drought of 2002, the water has flowed continuously for 130 years, giving life to the people and crops of Tropic Utah.
I spent two full days here, hiking through this magnificent landscape.
