People in our region find Great Falls both fascinating and perplexing. Arguably our most dramatic landscape feature, its origin and development remain obscure to many of us. We will take a relatively easy hike from the Great Falls (MD) Tavern Visitor Center to the falls overlook and adjacent areas along the towpath for a round trip of 1.5-2 miles. During the walk, we will discuss how the bedrock of the Great Falls area formed in tectonic collisions hundreds of millions of years ago and how the waxing and waning of the continental glacier led to the much more recent creation of the falls. Our geology walks move at a faster pace and over a greater distance than our usual naturalist’s shuffle. REGISTER
