California Natural World San Clemente Island Stories Underwater Life

The Kelp Forest :: Part II

It is my spirited opinion, one that I enjoy defending over a beer after a long day on the water, that diving amidst giant kelp is the most magnificent diving in the world. I am fortunate enough to have had some amazing experiences underwater -- watching swarms of hammerheads soar…

California Natural World San Clemente Island Stories Underwater Life

The Kelp Forest :: Part I

My first experience with seaweed was as a kid combing the shores of Newport Beach where I grew up. After storms my brother and I would find clumps of the brown stuff pushed up the beach. We would pick through them to pop the small bubbles attached to the leaves.…

One morning while diving at San Clemente Island I was struck by the lackluster light. It was cloudy and dark and I had yet to find any exciting subjects to shoot. I was spacing out in the shallows watching the kelp fishes meander among the weeds when I started fiddling…

Above the granite walls surrounding Yosemite Valley are found many examples of glacial erratic boulders.
