Forest cacti: an incredibly tall and slender Pilosocereus (left), and a coarser and more open-branched Cephalocereus (right) growing in a Jalisco dry forest.
El Salto Pueblo Nuevo, Durango "Pueblo de Madera", a remarkable town in the cold highlands where everything is based on wood- from building materials to heating
