More model informationGeological features and fossils tell the story of an ancient ecosystem. This boulder is a unique example of both. The size and shape of the ripples leave clues about the force and direction of the current, and the shell molds provide examples of what lived in this environment. Located in Chaco Culture National Historical Park, these features were exposed when a massive monolith of sandstone known as Threatening Rock collapsed on Pueblo Bonito on January 22, 1941. If visiting the park, you can learn about this rockfall event and see this boulder, along the trail at the pueblo.
