HUGE Peurto Escondito I remember waking up before dawn to what sounded like thunder. There had been a seismic shift off the coast and an unannounced ground swell was hammering the shore. It lasted a few hours after the sun came up and caused detriment to more than a few gnarlers that paddled out. It was earth shaking. Some of the clean up sets were a solid 20 ft. Unforgettable force of nature.
