The Alamo Hueco Site is a prehistoric archaeological site in Hidalgo County, New Mexico. The site was inhabited from 600 to 1350 A.D., a period which spanned the San Luis phase, the Mimbres phase, and the Animas phase. The inhabitants of the site built several adobe mounds; while the mounds have been extensively vandalized, two large mounds still contain hundreds of rooms and significant cultural deposits. Materials recovered from the site include ceramics, lithic scatters, and cobbles.[2]
