RAY BROOK — As peregrine falcon nesting season draws to a close, rock climbing routes around the Adirondacks have been reopened by the state Department of Environmental Conservation.

From spring into summer, many rock climbing routes around the Blue Line are closed by the DEC so that peregrine falcons can nest without being disturbed. The DEC and climbing communities work in tandem to monitor routes and nesting sites, and as nest locations are established, the DEC closes climbing routes.

According to DEC wildlife staff, as of Tuesday, all routes at Poke-O-Moonshine, Chapel Pond and Wilmington Notch are open to climbing. All routes at Crane, Shelving Rock and Sleeping Beauty mountains are open as well.

At Potash Mountain, near Lake Luzerne, several routes are still closed.

“Climbing routes Haley’s Nose and Goes Both Ways, as described on page 86 of ‘Adirondack Rock Volume 2, A Rock Climbers Guide, Second Edition,’ are closed,” the DEC wrote in an email. “In addition, the 4th class scramble to access the Pitch 1 ledge of most routes, is closed. All open routes must be led ground-up.

“DEC appreciates the cooperation of the climbing community. As peregrine activity continues to slow down additional climbing routes will be re-opening. Climbers are urged to always be cautious and observant while climbing and report any aggressive or agitated peregrine falcon behavior to the DEC Wildlife Office at 518-897-1291 or info.R5@dec.ny.gov.”
