Artifacts found in stratified layers at Hueyatlaco. Archaeologists including Cynthia Irwin Williams excavated at Hueyatlaco in the early 1960s Human-made artifacts were found in bed C, bed E, and bed I Bed I was clearly underneath the Hueyatlaco volcanic ash layer
Humanmade stone tools found at Hueyatlaco—archaeologists including Cynthia Irwin Williams excavated in the early 1960s. The artifact-bearing layers underlie 10m of fine-grained, water-laid deposits that are part of the Valsequillo gravels. The lowest site, El Horno, had tools found beneath volcanic ash layers. Even skeptics admitted there was no evidence of erosion in these layers.
