I tried to go XC skiing every morning while we were at Alyeska. I'd set the kids up with their downhill ski lesson, and then off I went to get in my time on the XC ski trails in the valley. The conditions were superb. One morning there was 3 or 4 inches of such dry powder that it was fast enough that I could skate ski with my tips underneath the snow. It made for completely silent skiing through the woods.
I also noticed that they seemed to groom the trails once a day, but perhaps this was because it was also snowing every day and they were just trying to keep up! With all the snow on the trees it was a winter wonderland. Patrick
