Kill site in the Valley of Mexico near Tepexpan, at which the butchered remains of two imperial mammoths were uncovered in association with flint and obsidian tools. It is important as an indicator of the rapidity with which newly arrived Asian hunters dispersed southward. Its geological context (the Becerra Formation) suggests a Late Pleistocene date which has been confirmed by a radiocarbon date of 7050 ± 250 be. Artefact associations, however, are something of a puzzle, since stone tools of both the Big Game Hunting tradition and the Old Cordilleran tradition were found in the same levels.
