A State Road Crew Watched a 100-Foot Animal Off Stinson Beach in 1983 — Every Man on the Crew Signed

In the autumn of 1983, five California highway workers witnessed a mysterious, nearly 100-foot-long creature moving through the ocean near Stinson Beach. Its dark body moved in strange, vertical coils, leaving witnesses struggling to compare it to any known marine animal. What makes this encounter even more mysterious is that the crew reportedly documented the incident on an official work stoppage form, complete with five signatures—but decades later, the document could no longer be found. A retired harbor patrolman named R.D. investigated the case and uncovered another reported sighting near Costa Mesa, hundreds of miles away, where a different witness described a remarkably similar, sewing-like motion. Could these encounters have involved an unknown marine animal, or was something else moving along the California coast? The witnesses' descriptions raise questions that remain unanswered. Explore this strange coastal mystery, the missing government record, and the possibility that something enormous may have passed through these waters long before anyone thought to look.
