Desert Series #2 - The San Felipe Desert

The other primary desert region in the Baja California Peninsula (in addition to the Vizcaino Desert) is the San Felipe Desert. According to Brittanica Encyclopedia Online, "Areas with a mean annual precipitation of 10 in. (250 mm) or less are generally considered deserts". They take up one-third of the Earth's land surface.

The San Felipe Desert is located in the northeastern portion of the Sonoran Desert. The Sonoran Desert is approximately 120,000 square miles and covers area in Arizona, California, Baja and Sonora, Mexico. This eastern desert area is drier than the Vizcaino region to the west and vegetation is sparse.

Over 140 species of cacti can be found in the Sonoran Desert, with an abundance of Cardon Cacti in the San Felipe desert region. Cardon Cacti are the largest cacti species (growing up to 70 ft high and weighing up to 25 tons) and have been estimated to live over 300 years. A previous blog entry describing the difference between Cardon Cacti and the similar-looking Saguaro Cacti can be found here: Cardon Cacti & Saguaro Cacti - One in the Same?

A popular tourist attraction in San Felipe is the natural Cardon Cacti reserve with many specimens to oogle and awe over. One of these was transported to Seville, Spain in 1992 for an exhibit in the World's Fair. Here is a fun read of the trials and tribulations transporting a giant cacti across the world, complete with original photos: The Cardon of '92.

The tourist town (with many relocated expats) of San Felipe is one of many in Baja where the desert - San Felipe region of the larger Sonoran Desert - truly does meet the sea (Sea of Cortez), unlike anywhere else in the world.

Desert Series #1 - The Vizcaino Desert

The Vizcaino Desert is a primary desert region of Baja located on the western side of the Peninsula. According to Wikipedia (online encyclopedia), "Deserts are defined as areas that receive an average precipitation of less than 250mm (10in). They take up one-third of the Earth’s land surface". Annual rainfall in this area is approximately 5cm per year (2 inches) - with additional moisture from condensation of Pacific Ocean breezes.

The Vizcaino Desert is just south of Vizcaino Bay and encompasses the coast from Barra San Juan to El Rosario and includes the following mountain ranges: Cerro Matomí, Sierra San Luis, Sierra San Borja, Volcán Las Tres Vírgenes, and Sierra San Francisco. It, and Vizcaino Bay that is adjacent to the desert areas, are named after the Spanish explorer Sebastian Vizcaino. A map of the area can be viewed here: Desert Ecology - Baja California Deserts. It is a minor portion of the larger Sonoran Desert that encompasses areas in Arizona, California, and Sonora, Mexico as well.

The vegetation of this desert area includes the following types of cacti: senita, barrel, candelbra, cholla and sour pitaya. It also contains boojum, elephant trees and agaves stem or leaf succulents and the desert shrubs slipper plant and ball moss.
