Sentinel of the Sonoran desert

Stretching from northwest Mexico up through southwest Arizona and California this swath of desert is a diverse ecosystem. It is home to a well-known native and an icon of the southwest, the Saguaro cactus. These magnificent cactus can grow up to 50 feet and live for 150 years. They stand sentinel over the Sonoran desert as if guarding this place with steely spikes. And, as it should. The Sonoran desert is a place of majestic beauty and a testament to the tenacity of life.
