Thor's Hammer, the left side of the photo, at Bryce Canyon National Park, Utah. Thor's Hammer is a spectacular example of a hoodoo, which is sometimes referred to as a tent rock or fairy chimney. They form because of erosion processes and may be found in badland areas whenever relatively hard rock overlays softer more erodible rock, such as sandstone. Thors Hammer is one the Iconic hoodoos in Bryce Canyon and can be seen from Navajo Trail.
