As speculation and fascination grow, the legend of the Monster of Crater Lake shows no signs of receding into the depths of this natural wonder. Whether its existence is fact or folklore, the creature from the deep continues to intrigue those who visit and contemplate the mysteries that may lie beneath Crater Lake’s calm waters.

Brief History of Crater Lake

Crater Lake, located in Oregon, is a breathtaking body of water that holds a rich history. The lake was formed approximately 7,700 years ago following the eruption of Mount Mazama, a volcano that was believed to reach up to 12,000 feet in height before its destruction. This eruption led to the creation of a crater around 6 miles in diameter, which later filled with water and formed Crater Lake as we know it today.

The Cascade Range, a volcanic arc that stretches through western North America, is home to Crater Lake and the remnants of Mount Mazama. Mount Mazama was once an imposing part of this range, but after the eruption, all that remains are the caldera and the deep lake within it.

Human interaction with Crater Lake can be traced back to the time of Mount Mazama’s eruption. The area has been a source of admiration, wonder, and folklore throughout history. On May 22, 1902, Crater Lake National Park was established to preserve the lake’s natural and cultural resources and share its astonishing beauty with the world.

Today, Crater Lake boasts an impressive depth of 1,943 feet, making it the deepest lake in the United States and the seventh deepest globally. Its pristine waters are among the clearest found anywhere in the world.

The history of Crater Lake unveils the fascinating story of how the dramatic power of a volcano can leave a legacy of unmatched natural beauty and intrigue.

Monster Sightings and Legends

Locals and Visitors’ Observations

In Crater Lake National Park, located in Klamath County, Oregon, sightings of a mysterious creature have grabbed the attention and imagination of all sorts of people. The lake, known for its fascinating depth, has been the subject of numerous reports describing a large, unidentified creature. Some people believe this creature to be the infamous Crater Lake Monster.

One account from a diver in the 1990s details an encounter with a creature measuring approximately 8 feet long and 3 feet across the mouth. The individual and their fellow divers allegedly observed the creature for at least five minutes, unable to comprehend the exact size and appearance of the unknown entity.

Another source of the lake’s mystique stems from the Klamath Indians, who consider it a sacred location inhabited by supernatural entities. According to local lore, the lake serves as a battleground for fierce conflicts between Skell, the “Spirit of Above,” and Llao, their version of the devil called the “Spirit of Below.”

Similarities to Loch Ness Monster

The existence of lake monsters across various parts of the world, including North America’s Lake Monsters, further supports the idea of a shared global fascination with these enigmatic beings. Whether real or folklore, the Crater Lake Monster remains a captivating legend, continuing to produce discussion and intrigue.

The Crater Lake Monster Movie


The Crater Lake Monster, released in 1977, follows a series of mysterious disappearances in the Crater Lake region of Oregon. The film features a dinosaur hatching from an egg that was unearthed by a meteor, which crashes into the lake and heats the water. The main characters, Dan Turner, Susan Patterson, and Arnie Chabot, seek to uncover the truth behind the strange occurrences and face the monster lurking within the depths of the lake. The Crater Lake Monster offers a thrilling adventure with key scenes of suspense and action throughout the film.

Cast and Crew

The Crater Lake Monster features a diverse cast, including Richard Cardella as Dan Turner, Glen Roberts as Arnie Chabot, Mark Siegel as Mitch Kowalski, and Bob Hyman as Jack Fuller. Additional cast members comprise Richard Garrison as Ross Conway, Kacey Cobb as Susan Patterson, Michael Hoover as Ferguson, and Suzanne Lewis. The film is directed by William R. Stromberg, who also served as the producer.

Production Details

The Crater Lake Monster’s box office performance was modest, with obvious holes in the plot that served as a point of criticism for viewers. However, the film remains a cult classic among B-horror movie enthusiasts. Its suspenseful atmosphere and engaging storyline continue to attract audiences, and the film is available for viewing on YouTube.

Scientific Explanations

Plesiosaur Theory

One possible explanation for the monster sightings in Crater Lake is the presence of a prehistoric marine reptile known as a plesiosaur. Plesiosaurs lived during the time of dinosaurs and went extinct around 66 million years ago. Some believe that one or more plesiosaurs could have survived and found refuge in Crater Lake, thus spawning stories and legends of the monster.

However, this theory faces strong scientific objections. Firstly, the timeline does not match, as Crater Lake was formed about 7,700 years ago, long after the plesiosaurs’ extinction. Secondly, surviving in the isolated environment of Crater Lake would be a significant challenge for any large marine organism due to factors such as the lake’s depth, temperature, and limited food sources.

Meteorite Impact

Another hypothesis attempts to connect sightings of the Crater Lake monster to a meteorite impact. Supporters of this theory argue that some meteorites could potentially carry organic compounds or even microorganisms, which upon impact might have transformed the lake’s ecosystem and led to the emergence of new species.

While meteorite impacts do have the potential to cause significant ecological changes, the likelihood of one giving rise to a large, unknown creature in Crater Lake is quite low. Astronomers have found no evidence of a meteorite impact in the lake’s history, and such an impact would likely have left noticeable traces in the surrounding area.

Moreover, any new species arising from a meteorite would still need to overcome the same challenges faced by the plesiosaur theory in terms of adapting to Crater Lake’s unique environment. Additionally, for any creature to remain hidden in the lake for centuries despite numerous scientific studies and underwater exploration, including the 1987 deep-sea rover expedition, seems highly unlikely.

While the existence of a deep-dwelling monster in Crater Lake remains a source of speculation, available scientific evidence does not support the theories of plesiosaurs or meteorite impacts as plausible explanations for the creature’s existence.

Mysterious Events and Disappearances

UFO Sightings

Over the years, Crater Lake has been a hotspot for UFO sightings. Some locals believe that the lake’s mysterious nature is connected to the presence of extraterrestrial life. Wizard Island, a volcanic cinder cone in the middle of the lake, has been particularly associated with these sightings.

Cave Drawings and Discoveries

Crater Lake’s extensive cave systems have also been a source of fascination for researchers, particularly Dr. Richard Calkins. In his quest to explore the unknown, Calkins discovered ancient cave drawings depicting unexplained creatures and events. These discoveries have fueled speculations that the lake may have been inhabited by otherworldly beings or witnessed supernatural events in the past.

One notable incident occurred in the 1990s, when Sheriff Steve Hanson discovered a severed head in a cave near the lake. Although an autopsy showed the cause of death as drowning, the head’s presence deep inside the cave remains an enigma.

The Monster of Crater Lake

In recent years, reports of unexplained fishing incidents and sightings of large, unidentified creatures near the lake’s surface have added fuel to the rumors of the monster’s existence. Some even speculate that this creature may be linked to the UFO sightings and the ancient cave drawings discovered by Dr. Calkins.

As with any legend, separating fact from fiction can be difficult. However, the many mysteries and eerie events surrounding Crater Lake and its rumored monster continue to captivate the minds of those who visit the area.


In conclusion, the Monster of Crater Lake is a fascinating topic for those interested in mysterious creatures and legends. The story of the Crater Lake Monster comes from a 1977 B-horror film, and it revolves around a plesiosaur that hatches from an ancient egg after a meteorite heats the waters of Crater Lake, California.

Crater Lake, located in Oregon, is a site of natural beauty and impressive depth. It is the deepest lake in the United States and the 3rd deepest in the world, measuring up to 1,949 feet deep.

While the Monster of Crater Lake may or may not exist in reality, it captures the imagination of people who appreciate a good mythical tale.
