Emergency Closure Alert

We will be closed today, June 25th due to extensive damage from last night’s storm along the parking lot and Forbidden Drive. Andorra Road is closed, and Northwestern Ave is impassable by vehicle after the Stables. There is currently no power or phone service at The Cedars House, The “Treehouse” Wissahickon Environmental Center, or Northwestern Stables; however we are all fortunate to find that our buildings were unscathed.


We are sad to report that our prized State Champion Cucumber Magnolia fell. A year of heavy rain and a large canopy allowed the strong winds to pull it down across Forbidden Drive. There is also a large amount of trees down on the trails of the Andorra Natural Area. Please avoid this area and keep a safe distance from crews working to clear the trails. If you come by to pay your respects to our tree, please practice caution and respect the City arborists removing its large branches from Forbidden Drive.
