Geology at Woodend November 21, 2010

Our Woodend Sanctuary sits firmly on the hard rock of Maryland's Piedmont province. The woods and lawns of today, however, hide evidence of a tumultuous history extending back half a billion years. We'll hike around the Sanctuary grounds and down onto the floodplain of Rock Creek, examining the topography and underlying bedrock to see how they bear witness to the long-term story. Our walk, mostly uphill and downhill over rocky and muddy terrain, will be 1 to 1.5 miles in length.
