In the winter of 1900, geographer Vaughan Cornish set out with his wife, Ellen, an engineer and artist, to Glacier National Park in Canada. Crossing through the North American wilderness on the Canadian Pacific Railway, they hoped to observe to see nature at its best.

What they ultimately discovered, was something so rare, they didn’t even know it was possible! Once they reached Glacier Park, it wasn’t long before they were met by one of nature’s most peculiar and awesome structures: “snow mushrooms.”

Describing them two years later in The Geographical Journal, Vaughan said: “When I attempted to detach a small snow-mushroom from its pedestal, I found that it was very firmly fixed. Having driven a long pole into the mass of snow, which was about 4 feet across, I found it to be tough and tenacious, and I was unable to dislodge it… I gave successive pushes until the tree rocked violently, when at last the snow-cap fell, but as a whole, and it was not broken with its impact with the soft snow beneath.”

For them to form, conditions have to be just right. The stumps have to be wide and tall, the snow has to be wet, and the wind can’t be too strong.

Snow mushrooms have been known to exist all over the world, but they’re still rare, which just makes it all the more amazing to look at them!

Those snow mushrooms that Vaughan and Ellen stumbled upon way back in 1900 were enormous! Sure makes you want to grab your snow gear and jump on top of one, huh?
