  Kettle (geology) - Wikipedia, the free encyclopedia
A kettle is formed when a large block of ice separated from a retreating (melting) glacier becomes buried by sediments.
Kettles are common features of areas of Canada and northeastern and north central US states that were covered by the glaciers of the ice age.
The Kettle Moraine is a region of Walworth and Kewaunee Counties, Wisconsin, covering a large area and has numerous kettle lakes some of which are 100 to 200 feet deep.

 General Geology of Plymouth County
The major geologic events which influence the development (genesis) and behavior of the soils in Plymouth County are; the formation of basement rock during the late Precambrian (Proterozoic) and Paleozoic era, the Pleistocene glaciation, and post glacial Holocene deposition.
The generalized surficial geology map for Plymouth County (377KB file) shows the type of sediments (surficial material) deposited by the glacier as it advanced through the area and the sediments deposited as the ice was retreating.
The outwash plains and moraines are "pitted" with kettle holes which were formed by blocks of detached ice that were buried in the sediment for many years until they melted leaving a depression.

 Kettlehole - Wikipedia, the free encyclopedia
A kettlehole (or kettle hole) is a small, usually round depression formed as a result of glacial action.
They are believed to form when a large piece of ice breaks from the edge of a retreating glacier, and becomes partially buried under glacial debris deposited by the glacier; after melting, this fragment leaves a small depression in the landscape.

 The Geobotanical Atlas: Regional Description, Glacial Geology
On a smaller scale, some of the complex glacial geology of the upper Kuparuk River area is due to the influence of permafrost, which underlies an active layer of variable thickness that freezes and thaws annually.
Such kettles have unvegetated, unstable flanks that steepen downward to near-vertical slopes at water level or that are broadly subject to slump and flowage.
Two kettles of this type have been identified in the upper Kuparuk area (Plate A), and others have been mapped at similar positions at the north flank of the Brooks Range farther to the west (Hamilton, 1982a).

Kettle lakes are commonly irregular in shape, size, and slope corresponding to the irregularities of the ice block (Wetzel, 1975).
In kettle lakes the sediment layers may be disrupted near the base and sedimentation rates are generally considered to be moderate to slow (1mm/yr to 1cm/yr) (Lakes and Environmental Change, 1999).
The second hypothesis is that the lake is a kettle hole, mainly because the elevation of the bottom of the lake is below the bed of the Mohawk and the deep end is large and nearly circular.

 Kettle Lakes near Woodworth, North Dakota   (Site not responding. Last check: 2007-10-04)
Kettle lakes are common features on the glacial landscape of North Dakota.
A kettle is a depression formed when a block of stranded, buried glacier ice gradually melted out --- causing the overlying land surface to collapse downward.
Where such kettle are deep enough to intercept the water table, a lake occupies the depression.

 Geology of Ice Age National Scientific Reserve of Wisconsin (Chapter 4)
In horizontal dimensions, those that are popularly recognized as 'kettles' seldom exceed 500 feet in diameter, but, structurally considered, they cannot be limited to this dimension, and it may be difficult to assign definite limits to them.
Sometimes the kettles prevail in the valleys, the adjacent ridges being free from them; and, again, the reverse is the case, or they are Promiscuously distributed over both.
Chamberlin's important role in the development of the concepts of glacial geology would not have been possible were it not for the clear observations and lucid writings of his predecessors of whom, in connection with the Kettle Interlo bate Moraine, only Charles Whittlesey will be singled out.

The Kettle Moraine is an area of varied topography--parallel, steep-sided ridges, conical hills and flat outwash plains, mostly composed of sand and gravel.
The Kettle Moraine area rises to 300 or more feet above the lands to the east and west yet is not a continuous divide.
It lies 20 miles to the west of Kettle Moraine at Greenbush, is completely covered by the moraine in the Waukesha County area, and is 8 miles east of the moraine at Elkhorn.

kettle, oval depression found in glacial moraines, which are landforms made up of rock debris.

The location that I chose, the "Kettle Hole Trail", is part of the Long Island Greenbelt Pine trail system that winds through the Pine barrens, and climbs from a glacial topography of outwash plain to a hummocky terminal moraine.
The Kettle Hole trail begins on the northern edge of the outwash plains and eventually climbs onto the Ronkonkoma Moraine, in an area that has been described at classically knob and kettle (Fuller, 1914).
Kettles are formed when large blocks of ice, left behind from the receding glacier, are covered by outwash sediments.

 Glacial Cape Cod, Geologic History of Cape Cod by Robert N. Oldale
The original kettle hole was far from round, but wave erosion and deposition along the shore have trimmed off headlands and closed off embayments in the shoreline much as they do along the ocean shore.
These early dates appear to occur in kettles that are underlain by fine sediments, which prevented or impeded the percolation of rain and snow melt.
Other kettle pond basal sediments are much younger and appear to indicate the time when the rising water table, caused by the rising sea level, first intersected the floor of the kettle hole.

The Kettle is open at the north-northeast end, and extends as a green valley some six miles, to the south fork of King’s River.
This rim of the Kettle is a beautiful illustration of the concentric or "dome-structure" of the granite of this region.
It has also a parapet along the south edge similar to that described as forming the rim of the Kettle; this is in places thirty feet high, and rises like a grand wall, with a narrow shelf on the north; from this there is a very steep slope down for a thousand feet or more.

Fifty thousand years ago - in a period known as the Pleistocene Epoch - the land beneath the Park was buried under a sheet of ice 1,000 feet thick.
The Wisconsin Ice Sheet also left behind depressions in the land known as "knob and kettle terrain." These "kettle ponds" formed the geological surface necessary to create the Park's watercourse, beginning with Fallkill Falls and continuing into the Ravine, Lullwater and the Lake.
Thick forests began to prevail about 8,000 years ago and, as the vegetation grew and the warming continued, diverse species of wildlife spread from the south and new ecosystems were born.
