Step back in time, all the way to the Jurassic Period 200 million years ago, when the Conway granite that forms the walls of the Flume were formed and see a deep basin that was formed at the end of the Ice Age.
The Flume Gorge is a 2 mile hike that takes about 1.5 hours, where you will discover waterfalls, beautiful mountain views, covered bridges and a scenic pool. The trail is well maintained but there is a lot of uphill walking and many stairs along the way.
The actual Flume is a natural gorge that reaches 800 feet at the base of Mount Liberty and discovered in 1808 by Jess Guernsey on a fishing trip. Along the trail you will also see Table Rock, which formed over time by the rushing waters of the Flume Brook exposed large outcropping of rock. After that you will soon see Avalanche Falls which was formed during a storm in 1883 that washed away a huge hanging boulder. This boulder hung suspended between the walls of the Gorge until the heavy rainstorm started a landslide that washed the boulder away.
While on this 2 mile hike you will come across the Flume Covered Bridge, which was build in 1886 and one of the oldest in the state. The bridge was built across the Pemigewasset River and visitors can view Sentinel Pine Bridge and the Pool. The Pool is a deep basin in the Pemigewasset River that was formed at the end of the Ice Age and is 40 feet deep. Above the Pool stood one of the largest Sentinel Pins in the state that fell during a hurricane in 1938. The giant pines trunk bridges the river above the Pool and is the base for the covered bridge.
