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.
