My first exposure to snow rollers was years ago, when I regularly snowshoed the river. I saw the phenomenon and was quite impressed.
This morning we received a few inches of new snowfall followed by clearing and a fair amount of wind. The temps were warming and topped out around 35° so the snow was really packing under my snowshoes today. But the woodland trails were a blast and I enjoyed being out. Snow rollers were forming from the drop of a crotch in a tree!
There was extra effort to run today because of the snow and drifting. I plowed through most of my ancillary trails and will need to consider running in the mornings to avoid warm temps the rest of the week.
Cut it short at 5 miles because of the deeper snow. More often than not, I felt like I was running on tennis balls because of packing snow in the bindings. The county had made a loop around the main trail with their groomer so those segments were more runnable. The warmup provided by the need to shovel my drive and sidewalk left me a bit sore on today's total efforts.
