For thousands of years the pass in the mountain range was an important aspect of the traditional LenapeMinisink Trail. From the pass, the trail led to a landing at the best place to ford what the Native Americans called the Fishawack (the Passaic River). The trail was a portion of the Great Trail and always had been used by the Lenape on their route to the Hudson River and south from their hunting grounds in what is now Sussex County. That traditional part of the Great Trail would become Route 24, and leads from the pass through Chatham, Madison, Morristown, Mendham, and Chester; it is called Main Street in all but Morristown, the county seat, which is dominated by a square in the center of its downtown. Route 24 was recently redirected around the old road in order to retain the historical downtowns of the colonial villages through which the trail led. The portion of the original path is now labeled Route 124.
