The Lion's Head trail between the fire road and treeline has lots of poorly consolidated, soft, deep snow. From treeline up it is a mix of deep drifts, snowfields, rocks and ice. The snowfields above the Alpine Garden Trail are very soft and deep and, although there was plenty of traffic in the afternoon, the wind kept filling in the tracks. The summit cone has just enough snow between the rocks to give your crampons a break. I picked up a spot of mild facial frostburn as a souvenir.
Poles are helpful away from the steeps.
Mt. Washington in winter is always a memorable experience. As one of the early risers, I had quite a time breaking a path through the snowfields above the Alpine Garden Trail. Plenty of others followed, although there were also a lot of turnarounds due to the wind.
