Cerro Prieto, Volcano in Mexicali Valley, Mexico
Cerro Prieto is a volcano in Mexicali Valley that rises about 223 meters (730 feet) above sea level in a desert region. The area is characterized by extreme temperature swings, with winters near freezing and summers reaching intense heat.
This monogenetic volcano formed near the intersection of the Imperial Fault and Cerro Prieto Fault, which are part of the East Pacific Rise system. Its formation is tied to the geological forces that continue to shape this tectonically active region.
The Cocopah people call this place Wee Ñaay, meaning Dark Hill in their language, and the name reflects its importance in their traditions and identity. Visitors can see how the landscape itself shaped the way local communities understood and named the places around them.
The area houses one of the world's largest geothermal power stations that generates electricity from underground thermal resources. This facility makes the location significant for renewable energy production in the region.
The surrounding desert supports specialized wildlife including deer, coyotes, rabbits, lizards, and rattlesnakes that have adapted to extreme conditions. This variety shows how life thrives even in the harshest environments around the volcano.
