Cuarenta Casas

Cuarenta Casas (translation: "40 houses") is an archaeological site in the northern Mexican state of Chihuahua. Construction of the site is attributed to the Mogollon culture. Located in Vallecito in the municipality of Casas Grandes, Chihuahua, Forty Houses is believed to be the southernmost site related to the period of Mogollon influence. The site consists of a series of cliff dwellings built in natural caves in the cliffs of Huapoca Canyon. The best known is the Cueva de las Ventanas (Cave of the Windows).

Early Spanish explorers named the site Cuarenta Casas (forty houses) based on their speculation of the total number of structures. The area consists of five main cave communities: Cueva del Puente, Cueva de la Serpiente, Nido del Aguila and Cueva Grande.
