It partially filled the valley with glacial debris and removed soil and weathered rock from the vicinity. The gorge was covered by glaciers during the Ice Age, but the ice sheet did not greatly change the surface. The basalt dikes eroded faster than the surrounding Conway granite, creating a deepening valley where the gorge is now. As the overlying rock was worn away, pressure was relieved and horizontal cracks developed, allowing water to get into the rock layers. Had this material ever reached the surface, it would have become lava flows.Įrosion gradually lowered the earth’s surface and exposed the dikes. Because of this quick cooling, the basalt is a fine- grained rock. The basalt crystallized quickly against the relatively cold granite. The basalt came from deep within the earth as a fluid material, and because of pressure, was able to force the Conway granite aside. As it cooled, the granite was broken by closely spaced vertical fractures which lay nearly parallel in a northeasterly direction.Sometime after the fractures were formed, small dikes of basalt were forced up along the fractures. Nearly 200 million years ago during the Jurassic Period, the Conway granite that forms the walls of the Flume was deeply buried molten rock.
The same storm deepened the gorge and formed Avalanche Falls. A heavy rainstorm in June of 1883 started a landslide that swept the boulder from its place. The rock was 10 feet (3m) high and 12 feet (3.6m) long. At that time, a huge egg-shaped boulder hung suspended between the walls. She had trouble convincing her family of the marvelous discovery, but eventually persuaded others to come and see for themselves. The Flume was discovered in 1808 by 93-year-old “Aunt” Jess Guernsey when she accidently came upon it while fishing. See the Pet-Friendly Parks Webpage for more information.

The walk includes uphill walking and lots of stairs. The entire loop takes approximately 1.5 hours and finishes at the Flume Building.

The Short Trail/Rim Path is closed and the only option is to complete the full 2 mile loop. The Flume Trail is a 2-mile loop starting at the check-in booths located in front of the Flume Building. The walls of Conway granite rise to a height of 70 to 90 feet and are 12 to 20 feet apart. The Flume is a natural gorge extending 800 feet at the base of Mount Liberty.
