Explore Outdoors ~ Frost Flowers

 

Out for a walk in the woods last month, we discovered these needle-sharp, spiky frost flowers decorating the thin ice of puddles. These frost flowers have nothing to do with plants. Instead, they are ice crystals that grow on tops of newly formed ice on ponds and lakes - and even on the Arctic Ocean. It has to do with how warm the air is compared to the water, and the granules of ice trapped on the puddle surface. Those nubby granules form perfect spots for nucleation and growth of these porcupine-like "frost flowers."

What's happening to puddles and ice in your backyard?
