Abstract: The topic relates specifically to practices we have been using at our ski area in order to: 1. reduce the effects of wind blown snow and "blowing snow" ie. rapid cornice buildup and, 2. the changing of drift patterns by mechanical means. Namely, moving snow with a groomer machine on ridge tops to reduce the buildup of cornices on the lee side of the ridge and maintenance of a road system on top of the ridges to assist in the grooming of main trail runs below the ridges to the base area. What this accomplishes is to grade/push snow buildup from the top of the ridge into the prevailing wind thus changing the angle of the up wind slope. What is achieved is to redirect the wind drifting to create an eddy current in order to deposit the snow on top of the ridge rather than over the lee side. This further reduces cornice buildup as you can then drive downhill from the maintained road and groom from the road directly in the fall-line.
