Located in a national park just a few miles upstream from downtown Washington, DC, Great Falls and Mather Gorge force the Potomac River over a series of steep, jagged rocks as it flows through a narrow gorge. The natural roar and sounds of the water provide a welcome change to the often bi-partisan political debates and man-made noise of Washington DC located just a short distance away. The park has managed to stave off the encroachment of modern development and remains in a very natural state as it has for hundreds of years. The river is dangerous in this area and about 7 people drown near here each year mostly due to alcohol related accidents. E-PL1 with 20mm & 45-200mm.
