A deep, steep-sided mountain pass, Franconia Notch is an old stream valley, ground to a u-shape by glacial movement. Natural erosional features, including landslide scars, stream-cut gorges, and one of the most extensive talus slopes in the eastern United States illustrate land-shaping processes.
Year designated: 1971
