Fossil Butte National Monument

More than 35 million years ago, a large body of water called Fossil Lake spread across present-day Wyoming. Although the lake has long since dried up, the fossils of its former inhabitants are exceptionally well-preserved in the arid desert landscape. Fossil Butte National Monument protects this remarkable archaeological site. As you hike around the butte, try to picture the lush tropical foliage that once lined the shores of the ancient lake, and keep an eye out for traces of the crocodiles, rays, and fish that swam in the water.
