Hiawatha Crater: The Massive 31km Impact Structure Hidden Beneath Greenland's Ice
Recent scientific discoveries have shed light on a catastrophic event that may have reset human civilization thousands of years ago. A massive 19-mile-wide crater discovered beneath Greenland's Hiawatha glacier resulted from an asteroid impact approximately 12,000 years ago. This cosmic collision involved a mile-wide iron asteroid weighing up to 12 billion tons, traveling at 43,000 miles per hour, and generating a force equivalent to a 700-megaton explosion.
To understand the magnitude of this event, consider that the Hiroshima atomic bomb was only 15 kilotons, while the Tunguska event of 1908 was equivalent to a 10-megaton explosion. This Greenland impact would have been 47 million times more powerful than Hiroshima. Coinciding with this impact was a mass extinction that eliminated 75% of North American mammals, including woolly mammoths, saber-tooth tigers, giant ground sloths, and other species that once roamed the continent alongside early humans.
Key Takeaways
A mile-wide asteroid struck Earth 12,000 years ago, creating a 19-mile crater beneath Greenland's ice with explosive force 47 million times greater than the Hiroshima bomb.
This catastrophic impact coincided with a mass extinction event that eliminated 75% of North American mammals including numerous species unfamiliar to most people today.
Scientific evidence of this cataclysmic event has existed for years but has faced resistance from mainstream academic communities, highlighting how groupthink can impede scientific progress.
Massive Crater Beneath Greenland's Hiawatha Glacier Discovered
Impact of the Enormous Iron Asteroid
The scientific community has made a remarkable discovery beneath Greenland's Hiawatha glacier - a crater spanning 19 miles across. This massive crater formation is the result of an iron asteroid impact that occurred approximately 12,000 years ago. The event likely triggered widespread devastation that may have reset human civilization development.
To put this catastrophic event into perspective, consider that the Hiroshima atomic bomb in 1945 released 15 kilotons of energy and devastated an area within a one-mile radius. The Tunguska event of 1908 flattened trees across 800 square miles with an estimated force of 10 megatons - 1,000 times more powerful than Hiroshima.
By comparison, the Greenland impact generated an explosion equivalent to approximately 700 megatons - about 47 million times stronger than the Hiroshima bomb. Evidence suggests this occurred while humans inhabited Earth, potentially explaining numerous mysteries surrounding lost ancient civilizations.
The Asteroid's Mass and Speed
The asteroid that created the Hiawatha crater was approximately one mile wide and composed primarily of iron. Scientists estimate its mass at between 11-12 billion tons - an extraordinarily large celestial object by impact standards.
This enormous space rock was traveling at approximately:
12 miles per second
43,000 miles per hour
70,000 kilometers per hour
Even using conservative estimates of around 10 billion tons, the asteroid's kinetic energy upon impact would have been devastating. The combination of its substantial mass and tremendous velocity created the equivalent of a 700-megaton explosion when it collided with Earth.
Crater Characteristics and Environmental Impact
The resulting crater measures 19 miles (31 kilometers) across and reaches depths of approximately 1,000 feet (305 meters). This significant geological feature had remained hidden under ice until recently, preserving evidence of this ancient impact event.
The timing of this impact event aligns with other significant Earth changes approximately 12,000-13,000 years ago:
Mass extinction of 75% of North American mammals
Disappearance of numerous megafauna species including:
Camelops (North American camels)
Giant ground sloths
Short-faced bears (larger than modern polar bears)
North American lions
Even today, areas affected by smaller impact events show lasting environmental effects. The Tunguska site still has a 1,000-foot circular area where vegetation struggles to grow more than a century later. The Hiawatha impact would have created far more extensive and long-lasting environmental changes across the planet.
Historical Significance of the Asteroid Impact
Civilization Reset
The asteroid impact that created the 19-mile-wide Hiawatha crater in Greenland represents one of the most transformative events in human history. Approximately 12,000 years ago, a mountain of iron nearly 1 mile wide and weighing between 10-12 billion tons collided with Earth at 12 miles per second (43,000+ mph). The resulting explosion generated force equivalent to a 700-megaton bomb—roughly 47 million times more powerful than the Hiroshima atomic bomb.
This cataclysmic event functioned as a planetary reset button for early human societies. Any civilizations existing at that time would have been instantly thrust back to primitive conditions, effectively erasing accumulated knowledge and technological progress. Evidence of this reset appears in archaeological records worldwide, showing abrupt changes in human activity patterns dating to this precise timeframe.
To understand the magnitude of this event, consider these comparative impacts:
Event Size/Power Damage Radius Year Hiroshima Bomb 15 kilotons ~1 mile 1945 Chelyabinsk Meteor 400-500 kilotons Damaged 7,200 buildings across 6 cities 2013 Tunguska Event ~10 megatons Flattened trees across 800 square miles 1908 Hiawatha Impact ~700 megatons Global effects ~12,000 BCE
The Tunguska event, 1,000 times more powerful than Hiroshima, still shows evidence today with a 1,000-foot circular area where vegetation refuses to grow. The Hiawatha impact, at 70 times Tunguska's power, would have caused worldwide devastation on an unimaginable scale.
Connection to Lost Ancient Human Civilization
The timing of this impact event at approximately 12,000 years ago aligns perfectly with several key pieces of scientific evidence that point to lost advanced civilizations. This period coincides with a mass extinction event that eliminated 75% of North American mammals—many species modern people have never even heard about.
These extinct North American species included:
Camelops - North American camels similar to modern Middle Eastern camels
Giant ground sloths - Massive creatures with claws larger than a human head
Short-faced bears - Significantly larger than today's polar bears
American lions - Lions that once roamed North America
All these species disappeared approximately 12,000-13,000 years ago—precisely when the Hiawatha crater was formed. This correlation strongly suggests that the impact triggered catastrophic climate changes that decimated these populations and potentially destroyed human civilizations that existed alongside them.
Despite compelling evidence, mainstream scientific and academic communities have been slow to connect these dots. The evidence has existed for years but has faced significant resistance. This phenomenon mirrors historical examples where groupthink mentality rejected revolutionary ideas, such as when Copernicus and Galileo faced opposition for presenting evidence about Earth orbiting the Sun.
Recent studies confirm that even intelligent individuals remain susceptible to tribal mentality that can impede scientific progress. The Hiawatha crater discovery provides physical proof of an event that likely erased significant chapters of human history, possibly including advanced civilizations whose existence we're only beginning to comprehend.
Comparative Analysis of Explosive Forces
Hiroshima Atomic Bomb
The Hiroshima atomic bomb of 1945 serves as a baseline reference for understanding catastrophic explosive events. With an explosive yield of approximately 15 kilotons of TNT, this weapon created devastating destruction within a one-mile radius, flattening an entire city instantaneously.
This event, while horrific in its consequences, represents only a fraction of the explosive potential observed in other natural cosmic impacts. When compared to larger celestial events, the Hiroshima bomb's destructive capacity appears relatively limited, despite its profound historical significance.
Tunguska Event
The 1908 Tunguska event demonstrates the immense destructive potential of atmospheric airbursts. This explosion over a remote Siberian region generated force equivalent to approximately 10 megatons of TNT—roughly 1,000 times more powerful than the Hiroshima bomb.
The impact flattened trees across 800 square miles of forest. More than 110 years later, evidence of this cosmic event remains visible, including a nearly 1,000-foot circular area at the epicenter where vegetation still struggles to grow.
Chelyabinsk Meteor
In 2013, the Chelyabinsk meteor provided a modern example of celestial impact forces. Though relatively small at only 20 meters (66 feet) wide, this meteor created a spectacular airburst approximately 18.5 miles above Earth's surface.
The resulting fireball glowed 30 times brighter than the sun, generating explosive force equivalent to 400-500 kilotons—about 26-30 times more powerful than the Hiroshima atomic bomb. Despite exploding at high altitude, which significantly reduced potential damage, the event still:
Injured more than 1,500 people
Damaged 7,200 buildings across six cities
Left virtually no meteorite fragments on the ground
These three explosive events provide important reference points when considering the recently discovered Hiawatha crater in Greenland—a 19-mile-wide impact site created by a mile-wide iron asteroid traveling at approximately 12 miles per second (43,000 mph), generating force equivalent to a staggering 700-megaton explosion.
Scientific Resistance Against Breakthrough Discoveries
History of Scientific Groupthink
Throughout history, scientific communities have often rejected revolutionary ideas despite compelling evidence. Nicolaus Copernicus faced significant resistance when he proposed the heliocentric model showing Earth orbited the Sun rather than the opposite. This fundamental astronomical truth contradicted established beliefs of the time.
Galileo Galilei later built upon Copernicus's work with observational evidence that conclusively supported heliocentrism. Despite his methodical approach and clear data, he faced potential execution for publishing his findings. The scientific establishment of the time—comprising many brilliant minds—collectively rejected evidence that contradicted prevailing theories.
These historical examples demonstrate how even intellectual communities can succumb to collective resistance against new ideas. The rejection wasn't based on scientific merit but rather on conformity to established thinking, demonstrating how human psychology affects scientific progress.
Groupthink in Modern Scientific Circles
Recent research confirms that groupthink remains prevalent in today's scientific and academic institutions. A study published in early 2025 demonstrated that even highly intelligent individuals remain susceptible to tribal thinking patterns that can hinder objective analysis.
This phenomenon is particularly visible in the scientific community's slow acceptance of evidence regarding the Hiawatha crater discovery in Greenland. This 19-mile-wide impact crater, created by a massive iron asteroid approximately 12,000 years ago, represents compelling evidence for a civilization-altering cataclysm that many researchers had previously theorized.
The impact evidence aligns perfectly with multiple independently verified scientific observations:
Evidence Timeframe Significance North American mammal extinction (75%) 12,000-13,000 years ago Coincides exactly with impact Camelops extinction ~12,000 years ago North American camel species Giant ground sloth disappearance ~12,500 years ago Previously thriving megafauna Short-faced bear extinction ~12,500 years ago Twice the size of modern grizzlies North American lion extinction ~13,000 years ago Little-known predator species
The asteroid that created the Hiawatha crater would have generated an explosion approximately 47 million times stronger than the Hiroshima atomic bomb. For perspective, the Hiroshima bomb (15 kilotons) devastated a one-mile radius, while the Tunguska event (10 megatons) flattened trees across 800 square miles and left vegetation unable to grow even 110 years later.
Despite overwhelming evidence connecting these extinction events to a single catastrophic impact, mainstream scientific institutions have been remarkably slow to integrate these findings into broader historical narratives, demonstrating how entrenched viewpoints can delay scientific progress.

Evidence of Catastrophic Events and Mass Extinctions
Connection to Major Extinction Episodes
The Hiawatha crater discovery in Greenland represents one of the most significant geological findings in recent years. This 19-mile-wide crater resulted from an asteroid impact approximately 12,000 years ago. The impactor, estimated to be nearly 1 mile wide, consisted primarily of iron and weighed between 10-12 billion tons. Moving at roughly 12 miles per second (43,000 mph), it created an explosion equivalent to a 700-megaton bomb—a truly world-altering event.
To contextualize the magnitude of this impact, consider that the Hiroshima atomic bomb yielded just 15 kilotons of explosive force, creating devastating damage within a one-mile radius. The Hiawatha impactor generated energy approximately 47 million times stronger than the Hiroshima bomb.
The Tunguska event of 1908, which flattened 800 square miles of Siberian forest, provides another comparison point. This air burst generated force equivalent to a 10-megaton bomb—yet the Greenland impact was 70 times more powerful.
Impact Event Explosive Force Damage Radius Hiroshima (1945) 15 kilotons ~1 mile Chelyabinsk (2013) 400-500 kilotons Multiple cities Tunguska (1908) ~10 megatons 800 square miles Hiawatha Impact ~700 megatons Continental scale
Scientific dating places this catastrophic event between 100,000 and 12,800 years ago, though mounting evidence suggests it occurred closer to the 12,000-year mark—a timeframe that aligns perfectly with other documented planetary changes.
Species Extinct Around 12,000 Years Ago
North America experienced a devastating mass extinction event approximately 12,000-13,000 years ago that eliminated 75% of its large mammal species. This timing correlates directly with the Hiawatha impact crater formation.
Many extraordinary species vanished during this period:
Woolly Mammoths: These iconic ice age mammals disappeared from most regions around 12,000 years ago
Camelops: Few people realize that camels originated in North America before going extinct locally
Giant Ground Sloths: These massive creatures had claws larger than a human head
Short-Faced Bears: Significantly larger than modern polar bears, nearly twice the size of grizzlies
American Lions: North America once hosted lion populations, a fact rarely taught in educational institutions
The extinction timeline for these species consistently falls within the 12,000-13,000 year range, creating a compelling correlation with the Greenland impact event. This alignment suggests that a single catastrophic event may have triggered widespread environmental changes, leading to the rapid decline of numerous megafauna species.
Despite this evidence, mainstream scientific communities have been slow to connect these patterns, demonstrating how academic consensus can sometimes delay the acceptance of new paradigms—a pattern seen throughout scientific history.
Lesser-Known Facts in American Natural History
Ancient North American Camel Species
North America was once home to a remarkable camel species called camelops. These ancient camels closely resembled the dromedary and Bactrian camels found in the Middle East and Asia today. Archaeological evidence confirms that these native North American camels thrived on the continent for thousands of years before their sudden disappearance approximately 12,000 years ago.
Modern paleontological research has established that camels actually originated in North America rather than the desert regions where they currently exist. This fact remains largely unknown to most Americans, as it rarely appears in standard educational curricula.
Prehistoric Megafauna of North America
The fossil record reveals that North America once supported massive creatures that dwarf their modern counterparts. The giant ground sloth (Megatherium) was among the most impressive, standing up to 20 feet tall when reaching on its hind legs. These herbivores possessed enormous claws, some larger than a human head, which they used primarily for pulling down branches and digging for roots.
The short-faced bear (Arctodus simus) was another formidable North American mammal. These bears:
Stood significantly taller than today's polar bears
Were approximately twice the size of modern grizzly bears
Had longer legs proportionate to their bodies, making them efficient runners
Became extinct around 12,500 years ago
Their remains have been found throughout the continent, yet they receive minimal coverage in standard educational materials despite being among the largest land carnivores to ever exist in North America.
North American Lion Populations
Contrary to common belief, lions once roamed across North America. The American lion (Panthera atrox) was larger than modern African lions and constituted a significant predator in the ancient North American ecosystem.
These magnificent cats disappeared from the continent approximately 13,000 years ago during a period of widespread extinction. Their existence represents an important chapter in North American natural history that few students learn about in traditional educational settings.
The fossil evidence of these lions has been discovered across multiple states, confirming their widespread presence throughout the continent prior to their sudden extinction.
