Skied the Northwest Trail today and it was in good shape (for both classic and skating). There is some leaf litter close to the southeast corner, but for the most part the trails were in great shape, and should stay that way into Sunday before next week's big melt. Even the black diamond hill bypass trails are groomed. Unfortunately there were four hikers behind me who ignored the park's many warning signs not to hike on groomed trails, and their actions may have damaged the trail.
