Looking at the California Channel Islands region today, it is the surface differences that strike the eye. Towering mountains marching right down to the sea, flat plains that are agricultural basins, valleys filled with homes, islands out in the sea, and vast development in the Los Angeles basin and surrounding valleys.

But what we don't immediately see is the geography that connected the entire region. From a bird’s eye view ( or a satellite image ) we could see the undersea canyons that extend from the shoreline out in to the Channel, and the underwater ridges that extend out to become the mountaintops we call the Channel Islands.

Let’s look at the influences that shape the physical form - geography - of the Channel Island region.
