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 ...
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 of sediment.
The Oak Ridges Moraine probably formed in the Late Wisconsin glacial period. Ice melt from the Niagara Escarpment flowed into the western boundaries of the moraine, wherein conduits beneath the ice expanded to form a west-to-east passage between the main Laurentide Ice Sheet and a mass of ice in the Lake Ontario basin.
The Harbor Hill Moraine, named for its prominence at Harbor Hill, Roslyn, New York, the highest point in Nassau County, resulted from a lingering equilibrium stage in the glacier's episodic retreat, creating a stationary melting front; [2] the Long Island area became permanently free of glacial ice in the range of 13,000 to 12,000 years ago.
The Ronkonkoma Moraine, a terminal moraine, predates the Harbor Hill Moraine (which reached Long Island during the Wisconsin Glacial Episode); the Harbor Hill Moraine cut through the Ronkonkoma Moraine's western portions. [2] The Ronkonkoma Moraine and the Harbor Hill Moraine intersect at Lake Success in western Nassau County. [2]

PPhysiography of the Valparaiso Moraine. Valparaiso Moraine at Mink Lake, north of Valparaiso, Indiana. The Valparaiso Moraine is a recessional moraine (a landform 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.
A fluted moraine, also called a fluted moraine surface, is a moraine whose surface exhibits numerous glacial flutes. The long axes of these flutes are parallel to the flow direction of the glacier. The long axes of these flutes are parallel to the flow direction of the glacier.
