Updates to White Mountain Guide, 30th Edition
Beginning on Monday, July 2, 2018, sections of the Tuckerman Ravine Trail will be closed due to two bridges being replaced. This closure will likely continue past Columbus Day. The detour will be on the Sherburne Ski Trail. Please see the official order from the Forest Service and a map of the closure area and detour for more information.

The U.S. Forest Service has closed the bridge on the Thoreau Falls Trail over the East Branch of the Pemigewasset River in the Pemigewasset Wilderness.
The posted signs say: “This bridge is not safe and is out of service. Do not plan to use the Thoreau Falls bridge as it has been partially decommissioned to prevent use in its current condition. Hikers should use good judgement and should have contingency plans in case fording the river at this location is not possible. For questions please contact the Pemigewasset Ranger District at (603) 536-6100.”
