One hundred forty million years before swimming pools dotted the hills, shallow seas bathed the land. We know this because Mount Diablo's layered rocks tell the story of the various landscapes, climates and life forms that once existed there. The trek is interspersed with opportunities to talk with experts about the natural history, geology, paleontology and plant and animal communities that existed on the mountain. Tired hikers will be refreshed by some of the grandest panoramas available in California. On a clear day the view extends from the Sierra crest to the sea-swept Farallon Islands beyond the Golden Gate.
