The land expropriated by the government was excavated by the National Institute and Anthropology and History (INAH), which found pre-Hispanic and colonial-era artifacts. The most significant of the pre-Hispanic finds was a child's burial, in which an obsidian bead with a duck's head, two other beads and deep plate-like objects called cajetes were found. The burial was found intact, mostly because of the fact that it was placed deep, about two yards under the first pre-Hispanic structure. Scattered around the site were more cajetes, mortars called molcajetes, dishes painted with eagles, serpents, and figures of Mexica deities, pieces of incensories, parts of musical instruments such as rattles and flutes, obsidian knives and needles made of bone and thorns. Most of these were found around a pre-Hispanic dwelling made of rock and compacted earth.
