The Mexican peninsula which is Baja California, separates the Pacific Ocean from the Sea of Cortez.

One of the youngest seas - its formation beginning 25 million years ago, the Sea of Cortez is one of the world's largest really deep gulfs. It is also said to be the richest sea in the world, both in terms of population sizes and number of species. For these reasons, the diving in Baja is fantastic.
