Glaciers and Music . . .

(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 "Ice age" was really a series of many advances and retreats of glaciers. The Finger Lakes were probably carved by several of these episodes. Ice sheets more than two miles thick flowed southward, parallel but opposite to the flow of the rivers, gouging deep trenches into these river valleys. Traces of most of the earlier glacial events have vanished, but much evidence remains of the last one or two glaciers that covered New York.

The latest glacial episode was most extensive around 21,000 years ago, when glaciers covered almost the entire state. Around 19,000 years ago, the climate warmed, and the glacier began to retreat, disappearing entirely from New York for the last time around 11,000 years ago. . ."

There MUST be music involved here somewhere. Yes, Keuka Lake is one of the finger lakes. . . and yet another iteration of my composition 'Keuka' demanded my attention this weekend. . .

Lakes. . .

(from wikipedia.com)
". . . Keuka Lake is an unusual member of the U.S. state of New York's Finger Lakes because it is Y-shaped, instead of long and narrow. Because of its shape, it was referred to in the past as Crooked Lake. Keuka means "canoe landing" in the Iroquois language and "lake with an elbow" in the Seneca language. Keuka Lake empties into another Finger Lake, Seneca Lake, from a stream, called Keuka Lake Outlet, at the lake's northeastern end in Penn Yan, New York. The stream empties into Seneca Lake at the village of Dresden. At one time the outlet was developed into a canal, the Crooked Lake Canal, connecting the lakes. This canal was later replaced by a railroad branch line which is now a hiking and cycling trail.

The lake is about 20 miles (32 km) long and varies in width from a half mile to two miles (1–3 km). The length of the shoreline is about 60 miles (96 km). It has a surface area of 11,730 acres (47 km²), and a maximum and mean depth of 186 feet (57 m) and 101 feet (31 m) respectively. This body of water possesses large and healthy populations of lake trout, brown trout, rainbow trout, landlocked salmon, smallmouth bass, largemouth bass, and yellow perch. The productive fishery is supported by huge numbers of baitfish, most notably alewives (sawbellies), and is a very popular lake with area fishermen. . ."

". . . 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 Athabasca Glacier in Alberta, Canada, is an example of a present-day glacier. The "Ice age" was really a series of many advances and retreats of glaciers. The Finger Lakes were probably carved by several of these episodes. Ice sheets more than two miles thick flowed southward, parallel but opposite to the flow of the rivers, gouging deep trenches into these river valleys.

The latest glacial episode was most extensive around 21,000 years ago, when glaciers covered almost the entire state. Around 19,000 years ago, the climate warmed, and the glacier began to retreat, disappearing entirely from New York for the last time around 11,000 years ago.

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. . ."
