The Hoodoos of Drumheller Valley are a unique geological formation located in the Canadian Badlands of Alberta, Canada. They are tall, thin spires of rock that stand atop a soft base of sedimentary rock. These formations were created through the process of erosion, which occurred over millions of years. The rocks that make up the Hoodoos are mainly composed of sandstone, siltstone, and claystone.

The Hoodoos are a popular tourist attraction, drawing visitors from all over the world. The area is easily accessible by car, and there are several hiking trails that allow visitors to explore the formations up close. The Hoodoos are also home to a variety of wildlife, including coyotes, foxes, and deer.

The formation of the Hoodoos is believed to have begun about 70 million years ago, during the Late Cretaceous period. At that time, the area was covered by a shallow sea that was rich in marine life. Over time, the sea retreated, leaving behind layers of sedimentary rock that were eventually eroded by wind and water. The resulting formations are a testament to the power of erosion and the ever-changing nature of the earth's surface.
