Details from the Monson Appalachian Trail Visitor Center: TRAIL CLOSURE ALERT: A pair of peregrine falcons with a young chick are nesting on the rock slide on the flank of Barren Mountain. If you hike near nesting peregrines, they may abandon the nest and their chicks may die. To protect this falcon family, the A.T. side trail leading to the Barren Slide has been closed. Breeding peregrines are endangered in Maine. Please respect the wildlife with whom you share the A.T. by obeying the closure.
