Nevado de Toluca is a broad edifice with a 1.5-km-wide summit crater that opens to the east. The northern flank rises here above the Zacango valley with a thin covering of summit snow. Two explosive eruptions during the late Pleistocene produced widespread ashfall and pyroclastic flow deposits. More recent work has revealed evidence for at least one Holocene eruption, about 3,300 years ago.
