Annual spring snow melt creates significant glide cracks, or crevasses, and undermined snow in the Lip area of Tuckerman Ravine. We close a section of the Tuckerman Ravine Trail where it passes through the Lip as a safety measure. This relatively short section stretches from Lunch Rocks in the Ravine to the junction with the Alpine Garden Trail just above the Ravine. Ascending or descending through this area now has numerous hazards which greatly elevate risk to travelers. The closure also pertains to skiers and riders. The closure only pertains to this section of the Tuckerman Ravine Trail and will remain in effect until melt out eliminates these specific hazards.
