The Story Behind the Snowflake

Imagine a snowflake so large you’d have to hold it with both hands. That’s precisely what onlookers in Fort Keogh, Montana, witnessed on a chilly day in January 1887. The account of a snowflake reaching 15 inches across, almost the size of a large pizza, boggles the mind. This wasn’t an ordinary snowflake; it was a flake of epic proportions, larger than anything we typically see falling from the sky today.

Fort Keogh: Where Nature’s Wonders Met Winter’s Fury

Fort Keogh, located near the Yellowstone River in southeastern Montana, was established as a military outpost in the late 19th century. Known for its extreme weather, it wasn’t unusual for snowstorms to sweep through the area, often piling up several feet of snow. But even seasoned residents at the fort were astounded by what they saw in January 1887.

The snowflake was recorded by soldiers and townspeople alike, sparking amazement and a bit of disbelief. With Montana’s vast skies and icy, bitter winters, Fort Keogh became a silent witness to this natural marvel.

How Does Such a Large Snowflake Form?

The formation of a snowflake depends heavily on temperature, humidity, and air pressure. Snowflakes typically form when water vapor in clouds freezes onto dust particles, forming ice crystals. But for a snowflake to reach 15 inches in width, unique conditions must have been at play.

Scientists believe that unusually large snowflakes like this one are likely a result of smaller flakes clumping together. Montana’s air in January can be quite moist and dense with suspended water droplets, creating the perfect environment for snowflakes to accumulate on each other as they drift to the ground. Instead of the delicate, intricate shapes we see under a microscope, these larger flakes appear more like soft, rounded clusters that gently pile up.

Documenting the Unusual: A Record That Stands the Test of Time

Though the 1887 snowflake’s record still stands, it’s challenging to scientifically verify such reports from the 19th century. Without photographic evidence or precise measurements, we rely on written descriptions passed down over generations. Still, the detailed accounts from multiple witnesses at Fort Keogh lend credibility to this remarkable record.

Even today, meteorologists and historians regard this as one of nature’s intriguing anomalies. The measurement itself—15 inches wide and 8 inches thick—might sound exaggerated to some, but the frigid climate and specific atmospheric conditions of Fort Keogh provide a plausible setting for a snowflake of this size.

Snowflakes of Extraordinary Sizes in History

This 1887 snowflake wasn’t the only oversized flake to make the news. In fact, records from various locations, particularly mountainous and polar regions, document large flakes that captured people’s imaginations. While no other reports have come close to 15 inches, several snowflakes measuring 4-6 inches across have been reported in colder climates.

Scientists studying snowfall and winter weather patterns use these accounts to understand how environmental changes might affect snowflake formation. Interestingly, as climate change impacts temperature and moisture levels globally, the conditions that create such giant snowflakes might become even rarer in the future.

A Fascination with Snowflakes – Small or Big

Snowflakes have captivated people for centuries, with their intricate designs often representing nature’s delicate handiwork. Today, even though we have advanced technology to study weather patterns and atmospheric conditions, snowflakes remain an enchanting mystery, each one unique and fleeting.

From the mathematical elegance of smaller snowflakes to the wonder of record-breaking ones like the one at Fort Keogh, snowflakes remind us of the beauty and unpredictability of nature.

Did You Know?

1. Not All Snowflakes Are Perfectly Symmetrical: While we think of snowflakes as symmetrical, they’re often lopsided due to uneven conditions as they fall.

2. The Science of Snowflakes: Snowflakes form unique shapes depending on the temperature and humidity at different altitudes.

3. Snowflake Photography: It wasn’t until the 1880s that Vermont farmer Wilson Bentley, known as “Snowflake Bentley,” captured the first photograph of a snowflake under a microscope, making people aware of their intricate structures.

Final Thought

While we may never see a 15-inch snowflake ourselves, the story of Fort Keogh’s enormous snowflake invites us to stay curious and appreciate the surprising wonders of our world—no matter how big or small.
