Look north from the Old Man and you will see another natural rock formation that mirrors the shape of a cannon. This is how Cannon Mountain received its name. Another highlight of the notch is the Flume Gorge. This area of the notch was first discovered in 1808. The gorge extends 800 feet at the base of Mount Liberty and its vertical walls rise 70 to 90 feet above the gorge floor.
Visitors walk along a boardwalk through the gorge.
At spots the walls are only 12 feet apart. After you pass through the gorge, you'll find that a nature trail meanders through the woods and returns to the visitors center, where you will find a gift shop and information center. To view the notch from another perspective, take a trip on the Cannon Mountain Aerial Tramway. In 5 minutes visitors can reach Cannon's 4,200-foot summit and take in fabulous views of the notch below and the surrounding peaks. Walking trails can be explored at your leisure, and you may spend as much time as you wish wandering about the summit.
