Rare Snowballs fall from Idaho Sky

Posted by on Wednesday, February 10, 2016

A rare weather event has produced spontaneous snowballs that fell from the sky back on January 30.

The snowballs are actually snow rollers. A snow roller is a rare meteorological phenomenon in which large snowballs are formed naturally as chunks of snow are blown along the ground by wind, picking up material along the way, in much the same way that the large snowballs used in snowmen are made. They can be as small as a tennis ball, but they can also be bigger than a car.

Unlike snowballs made by people, snow rollers are typically cylindrical in shape, and are often hollow since the inner layers, which are the first layers to form, are weak and thin compared to the outer layers and can easily be blown away.

It happened at the Nature Conservancy's Silver Creek Preserve and surrounding fields near the tiny town of Picabo.

Picabo is an unincorporated community in Blaine County, Idaho, United States. Picabo is located along U.S. Highway 20, about 10 km west of Carey, 31 km southeast of Hailey, and 50 km northeast of Shoshone.
