I've been up three times in winter on snowshoes. Each trip was via a different route. Finally did the usual NE ridge this past winter. It is the easiest route. All three were a lot of fun.
It was totally clear on the drive in until we crossed over the pass and from then on it snowed for the rest of the trip. No views and a severe wind chill on the summit, but fun all the same. Here is the route recorded by my GPS. It is a kml file and should be viewed in Google Earth.
