During late Pleistocene (Wisconsinan) time, the vast Laurentian Ice Sheet approximately 2-mile thick prograded southward to western Pennsylvania. This field trip to northern Butler and eastern Lawrence Counties will review the classic landscape features as evidence of the Last Glacial Maximum approximately 20 k.y. ago. With stops at the Jacksville Esker, the West Liberty Bog, the Muddy Creek Oilfield Exhibition, Slippery Rock Gorge, the Wisconsinan Terminal Moraine, Kame Gravel Pit and Cleland Rock.

Cleland Rock Overview

Not part of the trip, but certainly of interest to the theme of a changing climate landscape is the tundra biome. Tundra represents a colder climate usually associated with the high latitude treeless plain of the Arctic. During the Last Glacial Maximum tundra biome extended from the Wisconsinan terminal moraine at Moraine State Park as far south as Savanah, Georgia. In its wake, left relic climatic features within the Pittsburgh Low Plateau Section, such as, the rock city at McConnells Mill State Park, the Cranberry Bog, the late Wisconsinan Bridgeville Bog, and the flora of the Dolly Sods Wilderness Area in the Monongahela National Forest of eastern West Virginia.
