The Surge Of 1973 Alien And Cryptid Encounters

Reports of unusual sightings sharply increased in 1973. Nearly every day, individuals described encounters with strange, humanoid figures and mysterious, hairy bipeds, especially in wooded regions.

During this period, a notable event took place on Mount Lassen in Northern California. A group of seven boys camped on the volcano witnessed something extraordinary. As darkness settled, one boy wandered from the campfire and walked into the woods despite warnings.

While another boy followed to catch up with him, both heard an intense, guttural scream. The sound was both powerful and unsettling, echoing unnaturally close. Observing across a gully, the boy saw a large, upright creature, covered in dark fur, standing on two legs with two arms—features that closely resembled a humanoid.

Key details from the Mount Lassen encounter:

Detail Description Location Mount Lassen, Northern California Number of witnesses 7 (group of school friends) Incident time Night, in the woods Creature description Large, bipedal, dark fur, humanoid features Key experience Guttural, animal-like scream; close proximity

The group, unsettled and frightened, returned to camp and remained together throughout the night, unable to sleep. Early the next morning, there were questions about whether it was a man in a costume or something unknown. When rangers were contacted, the suggestion that it was Bigfoot came up during their conversation. The event reflects both the prevalence of such encounters in 1973 and the variety of interpretations—from hoax to actual cryptid—that marked this period.

Youth Encounter at Mount Lassen

Location and Camp Setup

In late 1973, a group of seven school friends embarked on an overnight camping trip on Mount Lassen in Northern California. They spent the evening gathering around a fire, surrounded by the dense darkness typical of the area. The volcanic setting, steeped in wilderness, provided a remote and quiet backdrop for their adventure.

Location: Mount Lassen, Northern California
Date: 1973
Group Size: 7 boys
Activity: Overnight hike and camp

Group Interactions and Events After Dark

As night deepened, one of the boys suggested walking along a nearby trail. Despite warnings about the dangers of hiking at night, he ventured out alone. Concerned, another boy followed after him, soon catching sight of his friend further up the trail.

Suddenly, a loud, unsettling howl echoed nearby. Described as a deep, powerful scream, it did not match any animal sound the boys recognized. The witness saw a tall, hairy, bipedal creature—humanoid in shape—standing across a small gully about 25 yards away. The animal’s fur was dark, and its presence left the boys frozen with fear.

A quick chain of events followed:

The boy ahead ran back to camp without a word.
The follower also fled, warning his other friend to run for safety.
All three regrouped, breathless, with the rest of the campers.

The group remained by the fire until morning, too scared to sleep. At sunrise, doubts surfaced about the encounter, leading to theories about hoaxes or costumes. After contacting park rangers, they were discreetly told about Bigfoot sightings, raising additional questions within the group.

Startling Scream and an Unusual Meeting

Following a Friend Into the Trees

After arriving at their campsite on Mount Lassen and settling around a fire, one member of the group chose to walk along the nearby trail. Even after being strongly warned against venturing out in the dark, the boy ignored the advice and left the safety of the firelight. Concerned, John decided to go after him to prevent any potential accidents in the nighttime woods.

Key details:

The group consisted of seven boys.
One set off into the dark woods alone.
John followed shortly after out of concern.

Sighting a Figure With Human-Like Features

As John trailed the other boy, he suddenly heard a loud, guttural scream; it was so powerful and unfamiliar that he could not identify its source or compare it to any known animal. Looking across a small gully, John saw a large figure partially visible in the low light. The figure appeared upright with two arms and legs, covered in dark hair, and was estimated to be about 25 yards away.

Feature Observed Description Stance Upright, bipedal Limbs Two arms, two legs Fur Dark-colored Distance Approx. 25 yards away Sound Loud, deep, guttural scream

Immediate Feelings and Group Reactions

John felt paralyzed with fear on seeing and hearing the creature. As soon as the boy he was following sprinted past him without a word, John turned and ran back toward camp, panicked. Another friend heading their way was told to turn and run as well. Once back at the campsite, the group decided to stay close together around the fire and remained awake all night, too unsettled to sleep.

Reactions at the campsite:

Panic and haste returning to safety
Group remained together, not risking a return trip in the dark
No one could sleep after the incident, choosing instead to stay by the fire

The next morning, John reported the incident to park rangers, seeking answers about what had occurred during the encounter.

Anxious Hours Around the Fire

The group of boys, unsettled by the encounter, remained tightly gathered by their campfire through the night. No one felt at ease enough to sleep. The fear of what they had seen—or thought they had seen—kept conversation minimal and every snap of a twig put everyone on edge.

Key Details of the Night:

The boys refused to leave the immediate area around the fire.
They kept alert, taking turns watching the darkness.
Any rustling in the woods led to bursts of whispered speculation and tense silence.

As the hours dragged, the campfire became their main source of comfort and safety. The experience left a lasting impression on everyone, especially John.

Questions and Explanations After Sunrise

When daylight finally arrived, the fear of the night before began to shift into doubt among the group. John, now less convinced by what he had witnessed, started searching for logical explanations. His thoughts turned to the possibility of a hoax, considering whether a person in a costume could have been responsible for what they saw.

Actions Taken the Next Day:

Step What Happened 1 John insisted they contact local park rangers. 2 He explained the situation and emphasized the potential danger. 3 Rangers responded quietly, suggesting “Bigfoot” could be responsible.

Discussions with the rangers only added to the mystery. Their vague response hinted at two possible scenarios: either a prank had been played by someone in the woods, or the encounter was something genuinely unknown and recognized by those familiar with the area.

Notifying Park Officials About the Experience

Speaking With Mount Lassen Staff

The next morning, John and the group decided to approach the staff responsible for Mount Lassen. John, being one of the older teenagers, took the lead in reporting the previous night’s alarming encounter. He clearly expressed to the park staff that someone had been roaming in the woods, possibly endangering lives.

Key Details Shared With Staff:

John emphasized safety concerns, fearing that someone could have been seriously hurt.
The description focused on a mysterious, humanoid figure covered in dark fur and emitting unsettling screams.
John's account underscored the urgency and seriousness of the situation, avoiding any exaggeration or speculation.

Possible Explanations and Staff Feedback

When John reported the encounter, one official quietly mentioned the possibility of it being “Bigfoot.” Their reaction introduced two main possibilities for what happened that night:

Possibility Description Prank by a Person The figure might have been a human dressed in a costume intending to frighten. Real Unknown Creature The staff’s response could mean acknowledgment of the existence of something unusual in the forest.

Staff did not openly confirm what the group encountered. Theories discussed by the staff suggested either a dangerous prank or a possible sighting of an unclassified animal, leaving the event unresolved but formally acknowledged.

Debate Over The Reality Of Bigfoot

Eyewitness accounts have led to ongoing questions about Bigfoot’s possible existence. In one notable incident from Mount Lassen, campers described seeing a large, bipedal, humanoid creature covered in dark fur. The group reported hearing an unusually loud and guttural scream, unlike any animal noise they had encountered before.

After the sighting, the possibility that a prankster in a costume was responsible was seriously considered. The idea of someone wandering remote forest trails at night in a suit was both plausible and concerning to them. When the campers reported the event to local rangers, the response was cryptic, with rangers quietly referencing Bigfoot rather than dismissing the claim outright.

Key Points:

Possible Explanations
- Large unknown creature (Bigfoot)
- Human prankster in costume
Authorities' Response
- Rangers did not provide a clear explanation
- The mention of Bigfoot suggested either knowledge of local legends or tacit acknowledgment

The ambiguity of the ranger’s reaction continues to fuel debate—either the authorities are aware of an unclassified creature, or such stories are perpetuated as part of local folklore. Direct evidence remains elusive, leaving witnesses and the public divided between skepticism and belief.
