How did Perito Moreno Glacier get its name?
The impressive Perito Moreno Glacier was first documented by Chilean explorer Juan Tomás Rogers in 1879. He initially named it “Francisco Gormaz Glacier” after a fellow naval officer. However, the glacier’s name would change a couple of decades later. In 1899, it was renamed “Perito Moreno Glacier” to honor the renowned Argentine explorer and scientist, Francisco Moreno.
The name “Perito” is actually a nickname meaning “expert” in Spanish, a fitting tribute to Moreno’s instrumental role in mapping this remote region of Patagonia. Beyond his exploration efforts, Moreno was a staunch advocate for Argentina, defending its borders during a time of tension with Chile.
Moreno’s passion for the glacier was evident in his dedication to understanding its formation and movement. His groundbreaking work in the region led to the decision to name this natural wonder after him, ensuring that his legacy lives on. Today, the name “Perito Moreno Glacier” rolls off the tongue, a constant reminder of Moreno’s significant contributions to our understanding of Patagonia’s captivating beauty.
How old is the Perito Moreno Glacier?
Given the awe-inspiring presence of the Perito Moreno Glacier, it’s only natural to wonder about its age – how far back in time does this icy giant actually go?
Scientists who study glaciers estimate that Perito Moreno began forming approximately 18,000 years ago, during the last Ice Age, a period when glaciers were far more common across the globe. Over millennia, snow accumulated in this region of Patagonia, and the immense weight of the snow compressed the layers below, transforming them into dense ice. This process eventually gave rise to the massive glacier we see today.
What makes Perito Moreno even more remarkable is that, unlike many glaciers today that are shrinking due to a warming planet, it continues to grow. The mountains surrounding the glacier receive an abundant amount of snowfall each year – we’re talking meters of snow! This snow transforms into ice, effectively “feeding” the glacier and contributing to its ongoing growth. In fact, Perito Moreno is one of the few glaciers worldwide that is defying the trend and continuing to advance.
It’s essential to recognize that even with ongoing research, scientists are still working to fully understand glaciers. 18,000 years is an incredibly long time, and while it’s the current best estimate for Perito Moreno’s age, ongoing research may reveal even more about its history. The natural world holds many mysteries, and the Perito Moreno Glacier stands as a testament to the ever-evolving nature of scientific discovery.

How Fast is the Perito Moreno Glacier?
We’ve touched upon the uniqueness of Perito Moreno Glacier, but let’s delve into the specifics of its movement. While many glaciers are retreating due to the impacts of climate change, Perito Moreno marches to the beat of its own drum, continuing to grow. It’s a true rebel in the glacier world!
So, how fast are we talking? This icy giant pushes forward into Lake Argentino at an average rate of about 2 meters per day. That’s quite impressive for something essentially a massive ice cube! To put it into perspective, it’s like the glacier moving the length of a car every single day.
Now, consider the force behind all that ice constantly advancing. Every few years, this relentless movement generates enough pressure to cause a massive rupture – it’s like the glacier is exhaling a giant, icy breath. These ruptures are incredible events, with massive chunks of ice dramatically collapsing into the lake, the sound deafening, like a powerful clap of thunder reverberating through the mountains.
Despite its impressive growth, the Perito Moreno Glacier isn’t entirely immune to the impacts of our changing climate. Scientists have observed some retreat in its northern front since 2020, a reminder that even the mightiest forces on Earth are feeling the effects of global warming.

While the future of the Perito Moreno Glacier remains a topic of ongoing study, one thing is certain: it stands as a powerful reminder of our planet’s dynamic and awe-inspiring nature.
Is Perito Moreno getting bigger?
We’ve talked about glaciers shrinking, but Perito Moreno seems to have missed the memo! This glacier is actually growing, which is quite unusual in today’s world. Scientists are still trying to fully understand this unique characteristic.
One factor that seems to be contributing to Perito Moreno’s growth is its location. Nestled within the Southern Patagonian Ice Field, it’s as if the glacier lives in a perpetual snow globe, receiving a constant influx of snowfall that adds to its mass. Its proximity to the ocean and its relatively lower elevation compared to some other glaciers mean that it’s ideally positioned to benefit from ample moisture.
But here’s where it gets even more intriguing. As Perito Moreno advances, it inches closer and closer to Lake Argentino, eventually forming a massive ice dam across the lake. As you might imagine, this dam causes the water level behind it to rise, building up pressure until the ice can no longer withstand the force. The result? A spectacular glacial rupture, where the ice dam bursts, sending enormous chunks of ice tumbling into the lake with a thunderous roar. It’s a truly awe-inspiring natural phenomenon.
Perito Moreno serves as a powerful reminder that our planet is in a constant state of change, even if those changes aren’t always immediately visible.

Why is the Perito Moreno Glacier blue?
We’ve discussed the impressive nature of the Perito Moreno Glacier, but have you ever noticed its striking color? It’s a mesmerizing, almost surreal blue that makes it stand out even more against the dramatic backdrop of Los Glaciares National Park. So, what’s the science behind this breathtaking phenomenon?
Think about how a prism works: white light enters, and a rainbow of colors emerges. A similar process occurs with the glacier. When sunlight hits the ice, not all colors are treated equally. The glacier is incredibly efficient at absorbing warmer colors like reds and oranges, leaving the cooler blues and greens to bounce back to our eyes, giving the glacier its characteristic blue hue.
But it’s not just about the light itself. The incredible density and tight packing of the Perito Moreno Glacier, with very few air bubbles or impurities that you might find in regular ice, play a crucial role. This density is key as it allows light to penetrate deeper into the ice before being reflected back out. The longer the light’s journey through the ice, the more of those warm colors are absorbed, resulting in a more intense and vibrant blue.
Interestingly, Perito Moreno is something of an overachiever in the world of glaciers. Unlike many glaciers that are shrinking due to climate change, this one is still growing! It advances at a rate of about 7 feet each day, and this constant growth helps maintain the glacier’s incredibly dense structure, which, as we’ve learned, is crucial for creating that captivating blue color.
It’s important to remember that scientific understanding of these natural wonders is constantly evolving. Researchers continue to study the Perito Moreno Glacier, and new discoveries may further illuminate the factors contributing to its unique color. One thing’s for sure: the Perito Moreno Glacier reminds us of the awe-inspiring beauty and complexity of the natural world.
How much does the Perito Moreno Glacier move a day?
Let’s focus on the movement of this icy giant. It might seem surprising that something so massive could be on the move, but Perito Moreno marches to the beat of its own drum, advancing at a rate of about two meters every single day. That’s right, this glacier isn’t content with merely existing – it’s on the move, pushing its way into Lake Argentino with the persistence of a slow-motion bulldozer made of ice.
To grasp the scale of this movement, consider that two meters is about the height of a tall basketball player. Now imagine a whole basketball team of ice just appearing every day! This constant growth is what sets Perito Moreno apart – it’s like a delicate balancing act: the glacier gains about as much mass as it loses, making it an anomaly in the world of glaciers.
But this movement isn’t always quiet and subtle. Perito Moreno has a flair for the dramatic, and every so often, all that pushing and shoving culminates in spectacular “calving events.” Imagine massive chunks of ice, sometimes even taller than buildings, breaking off the glacier face with a sound like thunder and crashing into the lake below. It’s a true spectacle of nature’s power.
Perito Moreno isn’t just a pretty face; it’s a dynamic force of nature, constantly on the move and reminding us of the incredible, ever-changing world we live in.
Is Perito Moreno Glacier Growing or Shrinking?
We’ve talked about Perito Moreno as a bit of a rockstar in the glacier world, but the big question remains: is it getting bigger, smaller, or staying relatively the same? It’s a bit complicated, but that’s what makes it so fascinating!
While it’s true that most glaciers are sadly melting away due to the impacts of climate change, Perito Moreno has chosen a different path. It’s actually pushing forward, advancing about 6 feet every single day, like a slow-motion bulldozer made of ice!
However, it’s not quite as simple as that. Even though it’s moving forward, Perito Moreno is still losing some ice through melting and those awe-inspiring calving events where large chunks of ice break off. Think of it like a bank account: even if you’re making deposits, you’re also spending money.
The good news is that for Perito Moreno, the “deposits” and “withdrawals” are relatively balanced at the moment. This means that it’s staying roughly the same size overall, even though it’s in a constant state of change.
Scientists are still working to unravel the mystery of why Perito Moreno is bucking the trend. Some believe that its unique location in the Andes Mountains and its unusual shape play a role, while others speculate that local weather patterns might be contributing to its growth. It’s like a giant puzzle, and researchers are carefully piecing together the clues to understand this incredible glacier.
One thing is certain: Perito Moreno is a powerful reminder that nature is full of surprises. It demonstrates that even in a changing world where many glaciers are struggling, some can still thrive.
