Snow Characteristics Comments

pretty good powder. Light top layer, still hitting the harder layer under the new snow and running over old tracks was easily noticeable. The wind seems to place more snow in some areas than others, so it felt like the depth changed a lot depending on shelter, elevations ans aspect.
