Officially declared extinct in 2018 by US fish and wildlife, the eastern cougar once roamed the forests of Pennsylvania and every state east of the Mississippi. The last officially documented sighting in Pennsylvania occurred in 1874 in Berks County, however residents still report sightings to this day. With 2 million acres of pristine and protected forests in the PA Wilds, it’s easy to believe this elusive cat, also called the ghost cat, could exist without a confirmed sighting.
