Ever seen a snowball roll itself?
Most residents of Kansas and Colorado hadn't either, until this winter.
Snow rollers, as seen in Russell County, Kansas
Recently, the rare combination of precipitation, temperature and wind
needed to create something called "snow rollers" has been present in
some parts of the Kansas and Colorado.
A snow roller is formed when a big snowflake hits the ground and bounces
a bit, traveling forward and collecting other snowflakes. When it gets
too heavy to bounce forward, it rolls, propelled by the wind. It
continues to roll and grow until the wind can no longer move it. The
resulting snow roller may be the size of a golf ball or may be the size
of a 30-gallon drum.
