As you know the scientific community and the world at large are now more accepting of the old sailor's tales of waves reaching 30-40 m in height. It's almost asking too much to believe that water could be piled up that high given its nature, but yet, I personally experienced a freak wave of this magnitude in 1963.Here's the GoogleEarth image he sent along to show where the encounter took place:
At the age of 14, we were living in the Lompoc, California, a small seaside community 5 miles from the Pacific Ocean. Fishing ,surfing, and other general contact with the ocean, where, and almost daily occurrences due to our proximity to the ocean. Of particular interest to my father and me, was collection of abalone at Point Conception, California. Since we are not scuba divers, these were collected off the rocks at low tide and the lower the tide, the bigger the abalone it seemed. This was quite an adventure for a 14-year-old teenager, have to scale cliffs climb down rickety ladders that shouldn't have held us at all. Then spend the day collecting abalone in 50 pound potato sacks and have to bring them back up the same dangerous cliffs and rickety ladders.
On this particular spring day in 1963, we are doing what I've already mentioned when my father who is a sailor noticed on the horizon what appeared to him to be a rather large wave. My father instantly warn me to hightail it to higher ground as he felt this way it was uncommon in size and that we were in grave danger. Me being a kid, I ducked into a hole thinking that I'd be protected. My father, thank God for his wisdom, reached and grab me by the hair and pulled me out of the hole. With no emergency in his voice. He pushed me and prodded me up the cliffside till we were as high as we could possibly get, in an effort to get out of harm's way.
Please remember that this was occurring at low tide, meaning that the water was probably 15 to 20 feet lower than normal at this point in time. We had a fishing partner with us, who was on the other side of the cliff when my father yelled to him to get out of harm's way. Instead of going to higher ground, he opted to go down to the beach and scrambled to the highest point of the beach, where beach meets Cliff. Just as we reached what my father felt was a safe area, we turned to look and watch the wave as it broke.
The point upon which we are standing at its lowest is approximately 80 to 90 feet above sea level, at slack tide. So by dead reckoning, we were actually somewhere between 90 and 100 feet above the sea level. I actually witnessed with my own eyes, this wave break over the surface of the cliff, and watched with amazement and fear as the Tower of water crashed down upon our fishing buddy on the beach. For what seemed an eternity, we lost sight of him. Then, as the wave ebbed, we saw him some 20 to 30 yards further down the beach lying in the sand completely drenched. His tackle box and fishing gear gone, his string of fish gone, but his life spared.
I've kept this memory with me for all of these years without sharing, because I didn't feel that this was something that was of interest. But then the current wave of interest that's generated on the Discovery Channel and science Channel have brought the recollection of this incident to the fore - front of my mind. I doubt I shall ever see another freak wave occurrence such as the one I have described, and quite honestly hope never to again. After everything is settled back to normal, and we resumed our abalone harvesting and fishing, my father pointed out the hole to me that I had climbed into and noted that it was now full of water 8 feet deep. Thank goodness I hadn't stayed in there I would most likely have been washed out to sea.

For those of us who are not familiar with Pt. Conception, I found this satellite image of a section of the
