I am so gravitated to this spot on the Oregon coast, called Thor's Well. Water shoots straight up this hole and waves come crashing in on either side of you. It's a dangerous, adrenaline-pumping experience.
Tides were particularly dangerous this day. In fact, the risk became a reality when a big wave came in and knocked me and my camera down. I was in full waders, but I was no match for the force of the surf.
I had one of my tripod legs wedged in between a couple rocks to keep the tripod stable. I was easily withstanding water that would come up to the knee. But the force of the wave (probably a little over waste high) bent my tripod's leg to a 45 degree angle and knocked me over. I've never experienced anything like it.
Fortunately I just scuffed my knee, and besides that, there was no major equipment damage.
I was lucky to get such wave action and a big sky to go along with it.
