The big picture

San Onofre nuclear reactors and the Cristianitos fault

A migrating shoreline

A vanished landmass

A growing fold

Perils of tampering with nature

An ice age sand lobe

Roots of ancient volcanoes

Sampling the mysterious Franciscan formation

A boon to communication

Wheeler Ridge

The San Andreas fault and Cajon Creek cooperate

Red Rock Canyon

A great natural geological laboratory

Young volcanoes in the Mojave Desert

Flamingos in the desert

Eighty seconds of catastrophe

A huge pile of living sand

A California rarity

Volcanic devastation

An intimate contact with volcanic phenomena.
