After I took each shot, I hid in my car just to the left of the tripod. These waves hit with such force that my car was shaken violently each time. Then I could wipe off the grad filter and get ready for the next attempt. It took about 10 tries to get it right. I wanted the iron post to not block the horizon and for the composition to be perfect. But that is difficult to do when you only get a few seconds to jump out of the car, take the shot, and dive back in. Finally I got the shot just as the park rangers ordered me to leave because people have been killed on this very spot!
The amazing thing is that this is on the bay-side of the bridge, the Pacific Ocean is on the other side of the bridge to the left. Only during strong westerly winds following a big storm with a high tide do these conditions exist. There were surfers out there and they were ordered back to shore too!
