Cathedral: The Fight to Save the Ancient Hemlocks of Cook Forest


This documentary tells the story of the hemlock trees of Cook Forest State Park, which are under attack by the hemlock woolly adelgid (HWA), a destructive insect that has already killed millions of hemlocks in the Eastern U.S.  HWA was discovered in Cook Forest in 2013.  The film takes the viewer on a journey through the forest in all seasons and shows the important work being done by the Pennsylvania Department of Conservation and Natural Resources and the Pennsylvania Bureau of Forestry.


Cost is $15/ticket.
