Satellite image of kettle lakes in Yamal Peninsula (Northern Siberia), adjacent to the Gulf of Ob (right). The lake colors indicate amounts of sediment or depth. A kettle (also known as a kettle hole, kettlehole, or pothole) is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters.
Lake Nipissing; 8,400 – 5,500 YBP formed as the water bodies in the Superior and Huron basins merged across Sault Ste. Marie around 8,400 YBP and then merged with the Michigan basin around 7,800. [1] Lake Stanley-Hough; 8,700 YBP, the water levels had risen to connect both Lake Stanley and Lake Hough into a single body of water. [1]
Lake Kankakee was a prehistoric lake during the Wisconsin glacial epoch of the Pleistocene Era. The lake formed during the period, when the Michigan and Saginaw lobes of the Laurentian glacier had receded back to the Valparaiso and Kalamazoo moraines. While the glacial advance became stagnant, the summer runoff formed a large lake covered parts ...
The bog began as a "kettle lake" formed approximately 10,000 years ago by a portion of the retreating Wisconsin Glacier (named according to geologic epoch, not location), which initially covered a depth up to the top of the current forest canopy. With restricted air and nutrient flow, sphagnum moss grew out into the lake, eventually forming a ...
The bog formed from a postglacial kettle moraine left behind about 14,000 years before the present by the melting of the ice sheet during the end of the last glacial period. The acidic bog is noted for pitcher plants and other wetland species. Access to the bog is restricted to ranger-led guided tours. [47]
The glacial origin of the Kettle Mucubají is evident because of the visible footprint left by the Mucubají ravine tens of thousands of years ago. This ravine was created by the action of a receding glacier, which was also sealed by an accumulation of unconsolidated glacial debris created by the lake. [1]
Glacial Lake Wisconsin 20,000 years ago with modern counties for geographical context. Glacial Lake Wisconsin was a prehistoric proglacial lake that existed from approximately 18,000 to 14,000 years ago, at the end of the last ice age, in the central part of present-day Wisconsin in the United States.
Before 600,000 years ago, Lake Corcoran covered the Central Valley of California. 600,000 years ago a new outlet formed in the present day San Francisco Bay, rapidly carving an outlet through Carquinez Strait, probably catastrophically, and drained the lake, leaving the Buena Vista, Kern and Tulare Lakes as remnants.
