PALACIO PRIETO, José Luis. Destrucción de tierras en el flanco oriental del Nevado de Toluca, el caso de la cuenca del arroyo El Zaguán. Invest. Geog [online]. 1988, n.18, pp.9-29. ISSN 2448-7279.

Changes in landuse and the presence of an erodible lithology (pumice lapilli) are the main factors controlling the accelerated erosion in the eastern slope of the Nevado de Toluca volcano, state of Mexico. A detailed geomorphological study of a small catchment allowed the recognition of several unstable sectors along the catchment, requiring prior attention in order to avoid problems due to silting in dams, roads and towns. Among the unstable sectors, first order streams and external portions in meanders developed in pumice lahars and tephra ace included.
