These snowballs weren’t made by the neighborhood kids. So who, or what, made them?
Answer
The wind.
If conditions are right, snow rollers can form when the wind blows large chunks of snow across the ground, causing the chunks to pick up more snow as they roll along. The center is often hollow as the inner layers are the weakest and thinnest, making them easy for the wind to blow out. Snow rollers are also known as snow donuts. Yum.
