Siberian lagoons form natural snowman visible from space

A satellite orbiting 705 kilometers above Earth captured something that looks almost too perfect to be real: a five-part snowman etched into the frozen landscape of Russia's Chukchi Peninsula. The shape spans 22 kilometers from top to bottom, making it roughly 600 times larger than the world's tallest recorded snowperson.

Landsat 8's camera caught this in June 2025, when the remote village of Billings and its surrounding lagoons were still locked in ice despite being one of the warmest months of the year. The mean daily minimum temperature hovers around minus 0.6 degrees Celsius. The lagoons themselves—elongated ovals separated by thin ridges—form the distinctive snowman silhouette when viewed from above.

But here's where the geology gets interesting. This isn't engineered. It's the product of processes that repeat across the Arctic's permafrost. Beneath the surface lie spear-shaped ice wedges, frozen into the ground year-round. When summer arrives, the soil above these wedges slumps as it melts, leaving shallow depressions that fill with meltwater and become thermokarst lakes. Consistent wind and wave patterns then aligned and elongated these lakes into the shapes we see today. The ridges separating them likely mark the edges of different ice wedges below.

Reindeer and early exploration

Billings itself has a layered history. The village was established in the 1930s as a Soviet port and supply point, but it's named after Commodore Joseph Billings, a British-born naval officer who enlisted in the Russian navy and led a surveying expedition between 1790 and 1794. His mission: find a Northeast Passage and map the Chukchi Peninsula.

The expedition never quite reached Cape Billings, but its members explored much of the peninsula and produced some of the first accurate maps proving that Asia and North America were separated by a strait. Winter, counterintuitively, offered the best conditions for this work. When ships became trapped in ice, the explorers moved to temporary camps and switched to reindeer-drawn wooden sleds. The peninsula's frozen rivers and lakes turned into solid highways—far easier to traverse than the muddy bogs that emerged in summer.

The Chukchi people living on the peninsula already knew this. They routinely used reindeer to haul both people and cargo, and a pair could comfortably carry hundreds of pounds for several hours daily. Reindeer have a crucial advantage over sled dogs or horses: they feed themselves by digging through snow and grazing on lichen, requiring minimal logistical support in an unforgiving landscape.

Historical accounts suggest the Billings expedition enlisted Chukchi people to manage and care for dozens of reindeer at times. Some non-Chukchi expedition members tried riding them too—with mixed results. Martin Sauer, the expedition's secretary and translator, reported falling "nearly 20 times" after about three hours on a reindeer, using a saddle without stirrups or bridle. He added that the saddle "at first, causes astonishing pain to the thighs." A reminder that mastering a new landscape takes more than good intentions.
