PA Route 248 runs directly through the gap, connecting the two Lehigh Valley cities Allentown and Bethlehem to the smaller Carbon County boroughs of Palmerton, Bowmanstown and Lehighton.

From 1898 to 1980, the New Jersey Zinc Company emitted sulfur dioxide at rates of up to 3,600 pounds per hour, killing plant life and animal habitats.

Twenty years later, a noticeable lack of tree density remains on the Palmerton side of the gap.

The nature center is home to approximately 15 miles of hiking trails, open to the public from dawn to dusk.
