Our Woodend Sanctuary sits firmly on the hard rock of Maryland’s Piedmont Upland. The woods and lawns of today, however, hide evidence of a tumultuous history extending back half a billion years. We’ll hike about 2 miles on woodland paths within the Sanctuary as well as neighboring Rock Creek Park, examining the topography and underlying bedrock to see what they can tell us about Woodend’s geologic story. The walk, sometimes uphill or downhill over rocky or muddy terrain, will move faster at a faster pace than our usual naturalist’s shuffle. REGISTER
