This means that it would only just fit in the entire area of California and Arizona combined!

3. It’s bounded by mountain ranges, forests, and other deserts

To the west, it’s bounded by the so-called “Peninsular Ranges,” a group of mountain ranges that stretch over 1,500 kilometers (930 miles) from the south of California all the way to the southern tip of the Baja California Peninsula.

To the north and northeast, the desert is bounded by the Mojave Desert and Colorado Plateau Desert, as well as the Great Basin. To the east and southeast, it’s bounded by the Arizona Mountains forests and the peaks of the Sierra Madre.

Finally, to the south it transitions into the “Sonoran–Sinaloan subtropical dry forest,” a specific ecoregion in the northwest of Mexico.

4. The desert has been divided into 5 to 7 distinct regions

One of the most remarkable facts about the Sonoran Desert is that it consists of multiple sub-region deserts, each with their own characteristics, especially related to vegetation.

A book published in 1957 by Forrest Shreve named “Vegetation of the Sonoran Desert” made a division of 7 distinct sub-regions. These were:

  • Lower Colorado Valley
  • Arizona Upland
  • Plains of Sonora
  • Foothills of Sonora
  • Central Gulf Coast
  • Vizcaíno Region
  • Magdalena Region

Today, the Vizcaíno and Magdalena regions are considered to be a separate desert on the Baja California Peninsula called the “Baja California Desert.”

The distinct sub-regions recognized today are:

  • Colorado Desert
  • Gran Desierto de Altar
  • Lechuguilla Desert
  • Tonopah Desert
  • Yuha Desert
  • Yuma Desert

5. It features a unique type of dune in North America

Within the Gran Desierto de Altar, which is located in the southern Sonoran Desert in Mexico, lies a national park named the “Reserva de la Biosfera el Pinacate (“Pinacate National Park”). This park consists of 2,000 square kilometers (770 square miles) of desert and mountainous regions.

The most famous feature of this park is that it contains the only active erg dune region in North America, a flat area of desert with swept-up sand and very little vegetation.

This area looks like the vision we have of a real desert, a truly remarkable sight!
