Looking at a map, check the Salton Sea’s location and continue that south into the Gulf of California in Mexico. It appears to be a natural breaking point, right where the Colorado River dumps into the Gulf.

Yep... That was once all part of the sea of Cortez, the geology points towards Baja once being an island with a strait at Palm Springs west through to San Bernardino. The Pacific plate has since pushed it up through subduction and is still pushing it up. That is a major crust movement zone right along through there as you say.
