I skiied Sunshine this past weekend and the mountain was in pretty decent shape for mid December. A 50cm+ storm cycle over 3 days left some nice fresh lines (under blue skies) on the Saturday, so there were some nice turns to be had, only negative was a very cold wind that made skiing on the upper mountain a bit frosty. On a clear day, a lot of the wide open terrain up high is great, but today was very windwespt. The best powder was on the sheltered slopes of Mt Standish - short but steep and sweet lines with lots of natural terrain features (banks, gullies, small drops). Standish is now a high speed quad (used to be a slower double) so it gets skied out fairly quickly, but seemed to have more snow than the rest of the mountain.
Also got in a run on Goat's Eye, the top was windswept but the lower treed runs were in excellent shape, loose powder on a good base and more consistent fall-line than other parts of the mountain.
Once again, Sunshine lived up to its rep as getting the most snow in the Banff area, as the snow reports indicated it had received much more snow than Lake Louise and Norquay this past week.
