Irene also did significant damage in the Adirondack Mountains, farther upstate. A section of NY 73 was washed out, isolating the hamlets of Keene and St. Huberts in the High Peaks region of Essex County. DEC reported that landslides too numerous to count had taken place on many of the High Peaks themselves, all of which are located on state Forest Preserve land. It closed the Dix and Giant wilderness areas and the eastern zone of the High Peaks Wilderness Area to the public due to the threat of additional landslides and damage to trail infrastructure. Marcy Dam was damaged by Irene and Marcy Dam Pond was partially drained. On September 8, DEC reopened some trails and trailheads in the High Peaks and Giant areas, warning hikers that there was still major damage in some areas. The same day, it closed all trails on property it managed in the Catskill Park in Greene and Ulster counties.
