In the high country, the roads are marked with snow stakes. These stakes can range in length from 10-30 feet and are there to show the snow plows where the edge of the road is so the plow doesn't go off the road. Eventually, the roads are closed for the winter (Trail Ridge about 1/2 way down the page you will see a pic of a snow plow and a snow stake).
this post where I showed the new block wall? This picture and the last picture are the same scene and you can actually see this scene in that earlier post.
It is snowing again and it's comin' on Christmas.
