Periglacial processes and landforms are described from the Cordillera Neovolcánica of central Mexico. Inactive rock glaciers are related to different late‐glacial and Holocene phases of permafrost conditions. Active discontinuous permafrost occurs above c . 4600 m ASL and appears to be from the Little Ice Age. The lower limit of late‐glacial rock glaciers is situated 500 and 600 m lower than during the Little Ice Age.
