The products of the last major eruption of La Malinche, which occurred about 3100 years ago, are exposed around the summit area and consist of a weakly stratified pumiceous ash and fine lapilli layer, along with associated ashflow and lahar deposits. Lahars originating from La Malinche reached the Puebla basin and contain pottery fragments, indicating that precolumbian settlements were affected by the eruption. Pocket knife provides scale.
