High Quality Content by WIKIPEDIA articles! The Valparaiso Moraine is a terminal moraine around the Lake Michigan basin in North America. It is a band of high, hilly terrain made up of glacial till and sand that reaches an elevation of near 300 feet above the level of Lake Michigan at its maximum height in Indiana and 17 miles wide at its maximum width in Indiana. It may be higher or wider in other states. It 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 the dolomite rock layers of the Lake Michigan basin. Where the glacier stopped, glacial till and sand was deposited, creating the hills of the moraine. After the Valparaiso Moraine was formed, the glacier retreated and formed the Tinley Moraine.
