One hundred years ago, on Dec. 31, 1914, the lighthouse at Trinidad Head was assaulted by a wave of monstrous proportions. Although the details are unclear, we know that the storm that produced the waves was unusual and that the wave was greater than 100 feet and perhaps much more. The only eyewitness was the keeper of the lighthouse at Trinidad Head at that time, Captain Fred Harrington, and here is his account of the notorious wave.
“The storm commenced on December 28, 1914, blowing a gale that night. The gale continued for a whole week and was accompanied by a very heavy sea from the southwest. On the 30th and 31st, the sea increased and at 3 p.m. on the 31st seemed to have reached its height, when it washed a number of times over (93-foot-high) Pilot Rock, a half mile south of the head. At 4:40 p.m., I was in the tower and had just set the lens in operation and turned to wipe the lantern room windows when I observed a sea of unusual height, then about 200 yards distant, approaching. I watched it as it came in. When it struck the bluff, the jar was very heavy, and the sea shot up to the face of the bluff and over it, until the solid sea seemed to me to be on a level with where I stood in the lantern. Then it commenced to recede and the spray went 25 feet or more higher. The sea itself fell over onto the top of the bluff and struck the tower on about a level with the balcony, making a terrible jar. The whole point between the tower and the bluff was buried in water. The lens immediately stopped revolving and the tower was shivering from the impact for several seconds.
