Small symmetrical kettle with shallow pond in typical knob and swale topography. The soil temperature and moisture regimes are cryic (frigid at the lower elevations) and typic ustic/udic. If the water table is high, the kettle will fill to become a kettle lake. When the ice melts, a kettle forms. theground;topography is mainly gently undu-lating, but there is also some knob-and-kettle topography;thinsoil. Types of Moraines-Glacial-1. Some high elevation cirque lakes also occur. Lakes occur in the glacial knob and kettle topography. The basins often contain water. Climate: Mean annual precipitation ranges from 35 to 80 inches, about 60 percent falling as snow. Any knob and kettle topography has long since been removed from the landscape. Knob & Basin Topography-Glacial-Also called knob-and-kettle topography, a hummocky landscape consisting of knolls or mounds of glacial drift in an area also interspersed with basins or kettles. Kettle Lakes Ice blocks calve off of glaciers and become buried in sediment. COVER. Hummocky: Hilly, knob-and-kettle topography. Typical knob and kettle topography characterizes much of the surface of the moraine, the maximum difference in elevation between the bottoms of the kettles and the tops of the knobs amounting to a little over 100 feet. A distinguishing characteristic from other parts of Ecoregion 47 is the lack of loess over the glacial drift. Any knob and kettle topography has long since been removed from the landscape. End (terminal) 2. Hedrick's Pond surrounded by "knob and kettle" topography is in foreground, tree-covered Burned Ridge moraine is in middle distance, and extending from it to foot of mountains is gray flat treeless glacial outwash plain. In places the stratified drift surface formed areas that did not have a broad, stream-graded surface. Figure 40.3. Hummocky knob-and-kettle topography typifies ground moraine. Schematic cross-section showing the lumpy landscape of the ‘pseudo-moraine’ developed by 880,000 years of limestone dissolution, as glaciation that has lowered the land surface 30 m or so. Knob-and-kettle topography or large isolated kames formed when stratified drift filled holes in the ice. The morainal ridges and hummocky knob and kettle topography contrast with the flat plains of ground moraines, former glacial lakes, and outwash deposits. These areas are mapped as ice-contact deposits. Download : Download full-size image; Figure 40.3.

The Greenbush Kettle, 2 miles south of Greenbush on the Kettle Moraine drive, has been favored with a geological marker sign for years.
