"Located in the Allegheny Mountains of Tucker County, Blackwater Falls State Park is named for the amber waters of Blackwater Falls, a 57-foot cascade tinted by the tannic acid of fallen hemlock and red spruce needles. The falls, along with a few of the park’s other features like Elakala Falls, Lindy Point and Pendleton Point Overlook, are some of the state’s most photographed spots." - Blackwater Falls State Park website
