Finger. . .

. . . lakes


(from http://www.priweb.org/ed/finger_lakes/nystate_geo3.html)
The Finger Lakes consist of 11 long, narrow, roughly parallel lakes, oriented north-south as fingers of a pair of outstretched hands. The southern ends have high walls, cut by steep gorges. Two of the lakes (Seneca and Cayuga) are among the deepest in North America and have bottoms below sea level. These lakes all formed over the last two million years by glacial carving of old stream valleys. Ithaca is located at the south end of Cayuga Lake, the longest and the second deepest of the Finger Lakes. Cayuga is 38.1 miles long and 435 feet deep (53 feet below sea level) at its deepest spot. The actual depth of carved rock is well over twice as deep, but it has been filled with sediments; there may be as much as 1000 feet of glacial sediment in the deep rock trough below the lakebed.

The Finger Lakes originated as a series of northward-flowing rivers that existed in what is now central New York State. Around two million years ago the first of numerous continental glaciers moved southward from the Hudson Bay area, initiating the Pleistocene glaciation, commonly known as the "Ice age."

The most obvious evidence left by the glaciers are the gravel deposits at the south ends of the Finger Lakes called moraines and streamlined elongated hills of glacial sediment called drumlins. Moraines are visible south of Ithaca at North Spencer, along Route 13 west of Newfield, and near Willseyville. Drumlins are visible northeast of Ithaca at the northern end of Cayuga and Seneca lakes in a broad band from Rochester to Syracuse.

The beauty of the Falls. . .

. . . From Wikipedia:
Taughannock Falls is located in the Town of Ulysses in Tompkins County, New York in the USA. The park is northwest of Ithaca, New York near Trumansburg, New York. The name Taughannock comes from the Algonquian-speaking Lenni Lenape (Delaware) Indians, referring either to chief Taughannock or the word taghkanic (great fall in the woods).

The main cataract of the falls is a 215-foot drop (66 m), making it 33 feet (10 m) taller than Niagara Falls. It is one of the largest single-drop waterfalls east of the Rocky Mountains.[2] The water flows through a long gorge with cliffs up to 400 ft high (120 m), characteristic of the area's gorges that give rise to the common "Ithaca is Gorges" bumper stickers and t-shirts. The waterfall and gorge comprise an example of a hanging valley that developed in a very similar fashion to the one at nearby Watkins Glen State Park. None of the local gorges were "carved by glaciers." In fact all of the gorges are post-glacial valleys carved by the streams that still run through them. It is the valleys over which the waterfalls hang that were eroded (over-deepened) by the advance of the Pleistocene ice sheets.

Visitors can reach an excellent view of the waterfall by walking along a 3/4-mile-long trail (1.2 km). The gorge trail is open all year long, unlike the rim trails which are closed to the public in winter. Visitors in autumn can enjoy the picturesque colors of the surrounding trees. Swimming under the waterfall is hazardous and strictly forbidden.
