I took a few pictures along the way and was excited to find a snow phenomenon that rarely occurs. It is called a snow roller or donut. Here is the definition:
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.
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, leaving what looks like a doughnut or Swiss roll. Snow rollers have been seen to grow as large as two feet in diameter.
The following conditions are needed for snow rollers to form:
- There must be a relatively thin surface layer of wet, loose snow, with a temperature near the melting point of ice
- Under this thin layer of wet snow there must be a substrate to which the thin surface layer of wet snow will not stick, such as ice or powder snow
- The wind must be strong enough to move the snow rollers, but not strong enough to blow them apart.
- Alternatively, gravity can move the snow rollers as when a snowball, such as those that will fall from a tree or cliff, lands on a steep hill and begins to roll down the hill.
Because of this last condition, snow rollers are more common in hilly areas. However, the precise nature of the conditions required makes them a very rare phenomenon.
The ones I took a picture of where probably made some time ago, but were still holding their shape. I noticed several along the road going to Cedar Run. It almost looks like some little elves were busy in the forest making sculptures.
Along with the snow donuts the ice falls were as beautiful as ever. The extreme cold we have experienced has made them very thick and colorful. Some blues and browns are seen by the human eye and a better camera than I had to take the above pictures.
Today there were a lot of turkeys and deer out in the sunny day looking for some acorns and other things to eat before we get more snow. Possible 1-3 tomorrow predicted and it looks like March isn't giving up the negative temperatures quit yet with a negative ten predicted Monday night. I don't know about anyone else but I am ready for a March meltdown. It has been a long, cold winter in Leetonia this year and it is far from over. Mountain girl, Paula, logging out.
