The Gulf of California Rift Zone (GCRZ) is the northernmost extension of the East Pacific Rise which extends some 1,300 km (800 mi) from the mouth of the Gulf of California to the southern terminus of the San Andreas Fault at the Salton Sink. The GCRZ is an incipient rift zone akin to the Red Sea Rift.
This extension of the East Pacific Rise is often referred to as the Gulf of California Rift Zone. The Gulf would extend as far as Indio, California, except for the tremendous delta created by the Colorado River. This delta blocks the sea from flooding the Mexicali and Imperial Valleys. Volcanism dominates the East Pacific Rise.
Hydrothermal vent diagram. Hydrothermal circulation, or the circulation of hot water, is a predominant feature of the Guaymas Basin. Hydrothermalism is mainly observed in the southern trough of the basin where hydrothermal vents make up a hydrothermal complex on the seafloor by creating mounds, chimney structures, and sediments.

The Delfin Basin (delfín is Spanish for "dolphin") is a pair of interconnected submarine depressions located on the seabed of the northern Gulf of California. [1] The northernmost of these is called the Upper Delfin Basin while the southernmost is called the Lower Delfin Basin.
The Alarcon Basin is a submarine depression located on the seabed at the southern end of the Gulf of California. The basin results from the activity of the southernmost spreading center in the Gulf. This spreading center has also produced the southernmost oceanic rift in the Gulf of California Rift Zone, the Alarcon Rise.
