The slope in the foreground is the surface of the Xico debris avalanche deposit, which formed at the end of the Pleistocene during the youngest of several edifice collapse events at Cofre de Perote volcano. The highly mobile avalanche traveled into the Río Pescado drainage and covers an area of at least area ∼73 km².
