There are numerous outcrops and quarries on the west shore of Green Bay, which is actually a drift-mantled dip slope dipping into the bay. This exposure of Ordovician-age bedrock is the Galena dolomite. We do not enter the Duck Creek Quarry, but observe from a vantage point on the edge.
Water seeping out of the rocks shows the movement of groundwater in the area.
Note that many seeps originate about 5 meters below the lip of the quarry at the base of one particularly thick layer. The quarry would fill with water if it were not pumped. A pipe runs up the right side of the quarry to carry pumped water. A nice example of microclimate. Dandelions are growing on the sunny south slope of the berm but not the shadier north slope.
