Castle Rock is a butte in the Colorado Piedmont region of the Great Plains.[1][2] An area landmark, it is located in as well as the namesake of the town of Castle Rock, Colorado.[3]

The butte's caprock consists of rhyolite, rock which is strongly resistant to erosion. About 37 million years ago, a volcanic eruption took place that covered the area around Castle Rock with 20 feet (6.1 m) of rhyolite. After a few million years, mass flooding and erosion of the volcanic rock gave way to the castle-shaped butte visible today.[4]
