The Saguaro Cactus is the monarch of the Sonoran Desert and one of the supreme symbols of the American Southwest. Many physical features help explain the Saguaro's ability to store and conserve water. Accordion like pleats allow the cactus to expand and hold water through its roots. Spongy flesh in its trunk and branches serve as a reservoir. The Saguaros collect water with a network of roots that lies about three inches below the desert surface and stretch as far from the main trunk as saguaros are tall. In a single rainfall, these shallow roots along with small root hairs that grow in response to the moisture may soak up as much as 200 gallons of water, enough to last the saguaro a year.
We did a bird walk with a ranger and saw about nothing....and drove on down the road!
