Cactus grow in such harsh environments that I find their size amazing. These cactus are Cardones, some of the largest in the world. They can grow to over 18 meters in height and one cactus plant can weigh as much as 25 tons. They live for hundreds of years and would have to survive many drought cycles as well as range fires and disease organisms. The cardones are the symbol for the two states of Baja Califonia. There are a number of other cactus in this photo including an ocotillo with red blossoms.
