It is hard to believe that millions of years ago the area we were standing in was covered by the tropical waters of the Gulf of California. This ancient sea extended north all the way to present day Palm Springs.
As we ventured into the Domelands area of the Coyote Mountains Wilderness, any doubts we had were quickly put to rest .
The area is rich with fossilized shells, ancient reefs and petrified sand dunes that seem strangely out of place in this hot, dry environment.
We spent some time exploring the million year old reefs, vowing to come back at some later date to explore the maze of narrow canyons and caves.
Great books on fossils and geology of the Anza Borrego Desert
