Coordinates: 41°30′37″N 87°3′29″W. Valparaiso Moraine at Mink Lake, north of Valparaiso, Indiana. The Valparaiso Moraine is a recessional moraine (a land form left by receding glaciers) that forms an immense U around the southern Lake Michigan basin in North America. It is a band of hilly terrain composed of glacial till and sand.
The Tinley Moraine is a moraine around the Lake Michigan basin in North America. It was formed during the Wisconsin Glaciation and is younger than the higher and wider terminal moraine called the Valparaiso Moraine, which is located farther from the lake than the Tinley Moraine. Compared to the Valparaiso Moraine, the Tinley Moraine is much ...
Hadley Hills. Coordinates: 42°54′11.4″N 83°25′30.6″W. The Hadley Hills are a rugged glacial moraine located in The Thumb of Michigan, that extend from northern Oakland County and into southern Lapeer County . The Hadley Hills surround the village of Hadley; [1] The highest points and most prominent outcroppings are: Pinnacle Point at ...
1.1.3.2 Interlobate ‘thumb’ of Michigan. 1.1.4 Lake Michigan Basin. 1.1.5 Lake Superior Basin. ... This a partial list of glacial moraines.
Lake Maumee was a proglacial lake and an ancestor of present-day Lake Erie. It formed about 17,500 calendar years, or 14,000 Radiocarbon Years Before Present (RCYBP) as the Huron-Erie Lobe of the Laurentide Ice Sheet retreated at the end of the Wisconsin glaciation. As water levels continued to rise the lake evolved into Lake Arkona and then ...
Lake Chicago. Map of middle stage of glacial Lake Chicago, USGS Report of 1915. Lake Chicago was a prehistoric proglacial lake that is the ancestor of what is now known as Lake Michigan, one of North America 's five Great Lakes. Formed about 13,000 years ago and fed by retreating glaciers, it drained southwest through the Chicago Outlet River.
Terminal moraine. A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile ...
The medial moraine is the double line of debris running down the centre-line of the glacier. Lateral moraines can rise up to 140 meters (460 ft) over the valley floor, can be up to 3 kilometers (1.9 mi) long, and are steeper close to the glacier margin (up to 80 degrees) than further away (where slopes are typically 29 to 36 degrees.
