The melting ice formed the Great Lakes, the Upper Peninsula and Lower Peninsula (in the Michigan Basin). 12800 BC Mastodons and other ice age mammals started to appear in the fossil record. 11000 BC to 9000 BC Archeological evidence of Paleo-Indians appeared, in the form of sharpened stone tool points known as fluted biface.
Somewhat smaller than Lake Michigan, Lake Chippewa extended through most of the Michigan Basin, north to the Straits of Mackinac, where there was a narrow channel which conveyed the lake's outflow over the now submerged Mackinac Falls to Lake Stanley. Its shoreline ranged from 10–30 miles (16–48 km) out from the present day Lake Michigan shore.
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
ST. JOSEPH, MICHIGAN - FEBRUARY 18: Ice builds up along a pier on Lake Michigan on February 18, 2024 in St. Joseph, Michigan. The Great Lakes shorelines have historically been ice-covered this ...
Nipissing Great Lakes was a prehistoric proglacial lake. Parts of the former lake are now Lake Superior, Lake Huron, Georgian Bay and Lake Michigan. It formed about 7,500 years before present (YBP). The lake occupied the depression left by the Labradorian Glacier. [1] This body of water drained eastward from Georgian Bay to the Ottawa valley.
It continues into Michigan as far as Montcalm County. [1] The moraine was formed during the Crown Point Phase of the Wisconsin glaciation. At this time the glacier covering the area had grown thin, so it was restrained by dolomite rock layers in the Lake Michigan basin. Where the glacier stopped, glacial till and sand was deposited, creating ...
