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 ...
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]
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. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased ...
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]
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 ...
Although Lake Bonneville and the Great Salt Lake are collectively one lake system, the name "Lake Bonneville" is applied to the lake during the period from 30,000 to 13,000 years ago, and the name "Great Salt Lake" since 13,000 years ago. [24] Lake Bonneville was anomalous in the long-term history of the basin. As the largest of four deep lakes ...
Amid torrential downpours, Death Valley National Park's valley floor has received a record 4.9 inches in the past six months, far surpassing the average annual rainfall of about 2 inches per year ...
These potholes are the result of glacier activity in the Wisconsin glaciation, which ended about 10,000 years ago. The decaying ice sheet left behind depressions formed by the uneven deposition of till as buried ice blocks melted in ground moraines. [1] These depressions are called potholes, glacial potholes, kettles, or kettle lakes.
