Question

why is waterfall originated on hanging valley?

Answer 1

Many if not most of our waterfalls in the Finger Lakes of New York can be classified as occurring in “hanging valleys.” That is, they have formed where gorges drop into larger valleys that were greatly deepened by the passage of glaciers; hence these side valley gorges were left suspended, or “hanging,” above these main glacial troughs. In this episode of Walk in the Park (#81, recorded on July 16, 2014 at PEGASYS Studios, Ithaca, NY), we look at the hanging valley waterfalls along the southern end of the Cayuga Lake valley near Ithaca, NY. Then we compare them with two of the most famous hanging waterfalls in the United States–Yosemite Falls and Bridalveil Fall in Yosemite National Park.
