May 29, 1971 · The last such ice advance is known as the Wisconsin glaciation. It began about 75,000 years ago and ended within the last 12,000 years. In its wake, it left behind the landscape we know today. Written in the hills, valleys and gently rolling countryside, the tracks of the glaciers can still be clearly seen.

Wisconsin lent its name to the most recent series of glacial advances and retreats: the Wisconsin Glaciation that lasted from about 100,000 to 10,000 years ago. Massive lobes of ice (up to 2 miles thick) collided here, causing tremendous pressure, friction and buckling of the land surface.

The Green Bay Lobe covered this Ecological Landscape during the last part of the Wisconsin Glaciation. As the Green Bay Lobe melted and retreated eastward, outwash was deposited over lower-lying surface features, so the Ecological Landscape now appears as a nearly level to rolling sandy outwash plain, pitted in places, with sandy heads-of ...

The Forest Transition was entirely glaciated. The central portion was formed by older glaciations, both Illinoian and pre-Illinoian, while the eastern and western portions are covered by deposits of the Wisconsin glaciation. Glacial till is the major type of material deposited throughout, and the prevalent landforms are till plains or moraines.

Even though this park is in the driftless area, the area the glaciers missed, the geologic features are partially the result of the last (or Wisconsin) stage of glaciation. During this glacial advance, the Wisconsin River was plugged near Wisconsin Dells.

Typical of southern Wisconsin; mean growing season of 155 days, mean annual temperature is 45.9 deg. F, mean annual precipitation is 33.6 inches, and mean annual snowfall is 39.4 inches. The climate is suitable for agricultural row crops, small grains, and pastures, which are prevalent in this Ecological Landscape.

Two Creeks Buried Forest provides a unique, precise record of the multiple glacial advances and retreats in this area during the Wisconsinan stage of glaciation. The historic forest became established between the Cary and Valders glacial substages.
