Over the years, I’ve posted photos of one of my favorite winter phenomena and a couple of years ago, blogger Sandra, from A Corner of Cornwall, told me there was a fancy name for it!
Sastruga (pl. sastrugi) It means: “ridges of snow formed on a snowfield by the action of the wind.”
When the wind screams off the lake, it sculpts the snow into constantly changing shapes . . . sastrugi.
Some are subtle.
Some are gorgeous, sinuous, and flashy.
It may look like striations in rock
Or waves of water, breaking
Or just plain peculiar . . .

This was from earlier this week. Those “duck bills” have an overhang of at least a foot!
Sastruga–A new word for you–you’ll need to use it three times, in a sentence, to make it your own . . .
Would you ever have a need for such a word, in your neck of the woods?
