Topic: Terminal moraine


  
  Moraine -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-21)
Moraine is the general term for debris of all sorts originally transported by (A slowly moving mass of ice) glaciers or ice sheets that have since melted away.
Terminal moraine: When balance is maintained between the melting of a glacier and its forward advance, the debris carried on (superglacial), within (englacial), and dragged along the bottom (subglacial) is dumped at that point and builds up a heterogeneous mass of the transported material called the terminal moraine.
The ground moraine from the melting of the great (From two million to 11 thousand years ago; extensive glaciation of the northern hemisphere; the time of human evolution) Pleistocene ice sheets is usually spoken of as (Unstratified soil deposited by a glacier; consists of sand and clay and gravel and boulders mixed together) till.

Interlobate moraine: If large glaciers and continental ice sheets advance irregularly so that their margins are lobate, when the margins retreat by melting the resulting terminal moraines of boulders, clay, and sand simulate the original interlobate shape of the glacier or glaciers, and therefore such moraines are called interlobate.

The debris left at the edge of the glacier’s extreme forward movement is a terminal moraine.
Similar moraines deposited during a temporary halt in the retreat of glacial ice are called recessional moraines.
The margins of the great ice sheets of the Pleistocene epoch are marked by terminal moraines stretching across North America and Europe.

Behind the terminal moraine is found a recessional moraine deposited when the ice sheet receded and stopped for a period of time.
Ground moraine is till that was lodged beneath the glacier and genrally found behind the terminal moraine.
An outwash plain forms ahead of the terminal moraine as melt water from the snout of a glacier deposits stratified drift.

 Pennsylvania Geological Survey: Open-File Reports–Picture Rocks Report Text
The terminal moraine of the second glacial epoch (Wisconsinan) was placed at the south end of the Finger Lakes in New York State (Valley Heads moraine).
Leverett (1934) revised the ages of glaciation in Pennsylvania, noting that Lewis' (1884) terminal moraine marked the edge of the Wisconsinan aged advance (last advance) of the glacier and that there was a discontinuous belt of Illinoian age and older deposits south of Lewis' border.
Crowl and Sevon (1980), on the basis of radiocarbon dating and degree of weathering, determined that Lewis' terminal moraine and the “Olean drift” throughout northeastern Pennsylvania was of late Wisconsinan age.

The moraine was described by Chamberlin (1883a, 1883b:261-298) as the terminal moraine of the Second Glacial Epoch and cited as the most important discontinuity in the Pleistocene epoch in Wisconsin.
Outside the moraine near the town line the limestone crest of the ridge is covered only by thin clay soil and scattered boulders which probably came from the moraine or the ice front itself.
Alden (1918:209-217) clearly recognized that not all of the drift in the Johnstown Moraine was deposited during the one substage, that the thickness of the drift varied markedly from segment to segment of the moraine, and that the outermost front of the Johnstown Moraine was not everywhere synchronous nor representative of equal periods of time.

Lewis noted that south of the terminal moraine in Jordan Township (southeast Sonestown quadrangle) in the Little Muncy Creek valley there “are deposits resembling till except in the scarcity of scratched boulders”.
In Penn township, (southwest part of the quadrangle) Lewis remarked that the terminal “moraine is indistinct and the region immediately north of it is remarkably free from drift”.
He thought that the terminal moraine in northwestern Pennsylvania was deposited during the last glacial advance (his second glacial epoch) but he gave three alternative interpretations for the age of the moraine in northeastern Pennsylvania.

 Terminal Moraine
This was where the great " Terminal Moraine" of the glacial epoch crossed the Delaware, recalling the "Ice Age," to which reference has already been made.
This "Terminal Moraine" has been traced and care-fully studied for four hundred miles across Pennsylvania, showing throughout a remarkable accumulation of drift materials and boulders, heaped into irregular hills and hollows over a strip of land nearly a mile wide.
It is inferred in the estimates of the duration of the glacier, from astronomical data, that the cold period began two hundred and eighty thousand years ago, the greatest cold being many thousand years later.

 GEOLOGY AND GEOGRAPHY OF THE NEW YORK BIGHT
The Harbor Hill Moraine represents the terminal moraine of the most recent advance of Wisconsin Stage glacier which reached its most southward advance about 18,000 years ago (it was probably completely melted in the NYC area in the range of 13,000 to 12,000 years ago).
South of the terminal moraines of the great ice sheet meltwater carried gravel, sand, and rock flour from the melting ice and deposited it on an extensive outwash plain that extended to the coastal areas to the edge of the continental shelf.
The evidence for a terminal moraine across the Verrazano Narrows region of the New York Harbor suggests that the river drainage was completely blocked (or even non-existent for a time under the ice) during the climax of the Wisconsin glacier.

 Studies in the Sierra by John Muir
During the long glacial winter, soil-material was poured from the range as from a fountain, borne outward by the mighty currents of the ice-sheet to be deposited in its terminal moraines.
For, at the period of the deposition of the main soil-belt as a terminal moraine of the ice-sheet, long finger-like glaciers extended down every one of these cañons, thus effectually preventing the continuance of the main terminal moraine across the cañon channels.
After the coarse, unbolted moraine soils derived from granite, slate, and lava have been well watered and snow-pressed, they are admirably adapted for the ordinary food and anchorage of coniferous trees, but further manipulation is required to fit them for special grove and garden purposes.

This is a view of Moraine Park, one of the most beautiful valleys in Rocky Mountain National Park, with the parallel ridges of snow-covered Stone's Peak in the upper right.
Eventually the terminal moraine was eroded away, the lake drained -- so the meadow which we see today is really formed by sediment that collected at the bottom of this lake.
Moraine Park was probably visited by unknown fur trappers in the early 19th century, but the first documented view of the valley was by Rufus Sage in November of 1843.

If one or more tributary glaciers coalesce with the main glacier the lateral moraines unite to form trains of debris on the surface of the glacier at or near its center, called medial moraines.
When balance is maintained between the melting of a glacier and its forward advance, the debris carried on (superglacial), within (englacial), and dragged along the bottom (subglacial) is dumped at that point and builds up a heterogeneous mass of the transported material called the terminal moraine.
If large glaciers and continental ice sheets advance irregularly so that their margins are lobate, when the margins retreat by melting the the resulting terminal moraines of boulders, clay, and sand simulate the original interlobate shape of the glacier or glaciers, and therefore such moraines are called interlobate.
