View of the short forest along the road near El Triunfo, south of La Paz. The basement rock is granite. Organ Pipe Cactus (Stenocereus thurberi) and Cardon Barbon (Pachycereus pecten-aboriginum) are the most apparent cacti and are partly obscured by the short trees. During the rainy season the hillside would appear green.
