Frightful Cave (Spanish: Cueva Espantosa) is a pre-Columbian archaeological site located in the state of Coahuila in northern Mexico. It was occupied on several occasions during the Archaic period by what seem to be nomadic hunter-gatherer groups and is an important source of archaeological evidence
concerning the ancient desert tradition of the Central Mexican highlands.
