Those maps are of the Reserva Ecologica del Chichinautzin and of the Nevado de Toluca - Valle de Bravo. They are topographic maps with most roads and of course with contour lines. The maps can be downloaded as single .img file which you can send directly to your Garmin GPS device (check Tips 'n Tools for more instructions).
