The last mile or so of the mighty River Dart in Devon UK., taken a couple of weeks ago from an elevated viewpoint some 250 feet above the river at the ancient historic port of Dartmouth.
As you look towards the estuary as the river narrows the ancient fortified Kingswear and Dartmouth castles sit each side of the river,still armed with the cannon that protected the port back in Elizabethan times during the war against the Spanish.
Not sure how much of the detail you can appreciate at this viewing resolution but I was amazed at the detail in that patchwork of farming fields more than a mile away when viewed full size.
