Fayette County’s Ohiopyle State Park, named for its waterfalls, sees an exceptional amount of precipitation each year. It is lush. It is biodiverse. But is it a rainforest? Appalachia claims several temperate (not tropical) rainforests, and at least one website lists Ohiopyle State Park as a northernmost example.
