I have lived in the mountains of Kentucky. Granted the mountains weren’t as big as where we are in the Jura. But, we got snow. Lots of snow. Yet, I had never witnessed snow markers or snow fences (pictured above) being put up during winter.
The first time I saw a snow marker was in the Black forest of Germany. We had gotten lost on the way back from visiting a village and ended up winding our way over and through quaint little villages and scenic farms. Along the sides of the narrow country roads were these snow markers. Again, let me stress narrow and winding country roads in the Black Forest of Germany during winter with some snow. It was as scary as it was beautiful.
Later, I saw snow markers in the Vosges in Alsace, France.
The first time I saw a snow fence was about two months ago. There were and still are some up around the school near our apartment.
In the photo above, the fence is used to keep the snow from a small dirt road which is used by a farm house.
A snow fence is a structure used to force drifting of snow to occur in a predictable place, rather than in a more natural method. Snow fences are primarily employed to minimize the amount of snow drifting onto roadways. In rural areas, farmers and ranchers may use temporary snow fences to create large drifts in basins for a ready supply of water in the spring.
When I lived in Kentucky and Ohio there were times that snow markers and snow fences would have been practical. However, I have never seen them being used in the States.
Perhaps, in places like Michigan, Colorado or Utah they are used?
