On December 31, 1914, the largest recorded ocean wave ever to hit the United States West Coast struck Trinidad Head. At 4:40 p.m. local time, United States Lighthouse Service Captain Fred L. Harrington, the lighthouse keeper at Trinidad Head Light from 1888 to 1916, observed a huge wave about 200 yards (180 m) offshore approaching the bluff on which the lighthouse stood. He reported that the wave — which seemed to him to rise to a height even with the lens of the lighthouse 196 feet (60 m) above sea level — washed completely over 93-foot-tall (28 m) Pilot Rock offshore, then broke over the top of the 175-foot-tall (53 m) bluff, submerging the area between the lighthouse and the bluff, with water reaching the lighthouse's balcony. His report that the wave crested as high as the lens and that water reached the balcony suggests a possible wave height of 200 feet (61 m). The wave's impact shook the lighthouse and extinguished its light, although Harrington restored service in four hours.[8][9][10][11][12]
Much of Trinidad Head was transferred from the United States Coast Guard to the city of Trinidad in 1983. The 46 acres (19 hectares) transferred to the city came with the condition that the property be maintained for public recreation. The city zoned it as "open space" and opened a hiking trail around Trinidad Head in 1984.[13]
The National Aeronautics and Space Administration's (NASA's) Advanced Global Atmospheric Gases Experiment (AGAGE) began observations of key ozone-depleting substances and greenhouse gases at Trinidad Head in 1995. The site was updated in May 2005 with a system which measures more than 40 trace gases involved in stratosphericozone depletion, climate change, and air quality.[16]
The Bureau of Land Management manages the promontory cooperatively with the City of Trinidad, the Trinidad Rancheria, the Trinidad Museum Society and the Yurok Tribe.[14]
