9 Unsolved Mysteries in the Pacific Northwest That Still Puzzle Investigators

D.B. Cooper Hijacking (Washington, 1971)

In November 1971, a man known as D.B. Cooper hijacked a plane flying out of Portland, demanded $200,000, and parachuted somewhere over Washington state. Despite one of the largest investigations in FBI history, he was never found.

The case remains one of the most famous unsolved mysteries in the United States, with theories ranging from survival in the wilderness to an inside job. The rugged terrain of the Pacific Northwest only adds to the intrigue.

The Oakville Blobs (Washington, 1994)

Residents of Oakville, Washington reported a strange gelatinous substance falling from the sky during multiple rainstorms in August 1994. The blobs were described as translucent and jelly-like, covering cars, rooftops, and fields across the small town.

Shortly after exposure, several people reported flu-like symptoms, and pets in the area also became ill. Samples were tested by labs, but results were inconclusive and sometimes contradictory. No official explanation was ever confirmed, leaving the Oakville Blobs as one of the most bizarre and unexplained weather-related incidents in the Pacific Northwest.

Maury Island Incident (Puget Sound, 1947)

In June 1947, a harbor patrolman near Maury Island in Puget Sound claimed to witness several donut-shaped flying objects hovering overhead. According to his account, one of the objects began to malfunction and dropped debris onto his boat, injuring his son and killing his dog.

The incident quickly drew attention from military intelligence, making it one of the earliest reported UFO cases in U.S. history. While some investigators later suggested it may have been a hoax or misidentified material, others pointed to inconsistencies and missing evidence. Decades later, the Maury Island Incident remains a key part of Washington’s unexplained history.

Granger Taylor Disappearance (British Columbia, 1980)

Granger Taylor was a skilled mechanic from Vancouver Island known for rebuilding old machinery and even constructing a replica flying saucer. In 1980, he left behind a handwritten note claiming he had been invited on an interstellar journey with extraterrestrials.

He was never seen again. Investigators later found evidence of a possible explosion in the woods, but no definitive proof confirmed what happened to him. Whether it was an elaborate disappearance, a tragic accident, or something stranger, Taylor’s case continues to fascinate those interested in one of the Pacific Northwest’s most unusual mysteries.

Cadborosaurus Sightings (Pacific Northwest Waters)

For generations, residents along the coasts of Washington and British Columbia have reported sightings of a mysterious sea creature often referred to as “Cadborosaurus,” or “Caddy.” Descriptions vary, but many claim it resembles a long, serpent-like animal with a horse-like head.

Sightings date back to Indigenous oral histories and continue into modern times, with reports from fishermen and boaters. While some scientists suggest misidentified marine animals could explain the sightings, no conclusive evidence has ever confirmed the creature’s existence, keeping the legend alive.

The Keddie Cabin Murders (California, 1981)

In April 1981, four people were found murdered inside a cabin in the small resort town of Keddie, California. The crime scene was unusually violent, and the case quickly drew widespread attention due to its brutality and the lack of a clear suspect.

Over the years, investigators have revisited the case multiple times, uncovering new evidence and identifying persons of interest. Despite these efforts, no one has ever been definitively charged or convicted. The mystery surrounding what happened inside that cabin continues to draw attention decades later.

The Zodiac Killer (California, 1960s–70s)

The Zodiac Killer carried out a series of attacks in Northern California during the late 1960s and early 1970s, targeting couples and sending cryptic letters to newspapers. Some of these messages included coded ciphers, only a few of which have ever been solved.

Despite one of the most extensive investigations in American history, the killer was never officially identified. Numerous suspects have been proposed over the years, but none have been definitively confirmed. The Zodiac case remains one of the most infamous unsolved mysteries on the West Coast.

The Black Dahlia Murder (Los Angeles, 1947)

In 1947, Elizabeth Short, later dubbed the “Black Dahlia,” was found murdered in Los Angeles in a case that shocked the nation. The crime scene and media coverage were both highly sensational, drawing intense public attention.

Police interviewed numerous suspects and pursued multiple leads, but the case was never solved. Over the years, theories and alleged confessions have surfaced, yet none have led to a definitive conclusion. The Black Dahlia remains one of the most enduring unsolved cases in American history.

Fresno Nightcrawler Sightings (California, 2007–present)

In 2007, a home security camera in Fresno, California captured footage of a strange, humanoid figure walking across a front yard. The figure appeared to have long legs and no visible arms, moving in an unusual, almost gliding motion.

Additional sightings and videos have surfaced over the years, sparking debate online. Some believe it’s a clever hoax or misinterpretation of shadows, while others argue it’s something unexplained. Regardless of the explanation, the Fresno Nightcrawler has become one of the West Coast’s most talked-about modern mysteries.
