Willamette Falls

On the eponymous river, seen from the promenade accessed from the Oregon City Municipal Elevator. The low masonry building to the right of the falls is a hydropower plant, first constructed in 1889(!) and still in use. It was the first long-distance generating plant in the US, sending electricity 14 miles (23 km) to Portland. The foreground view isn't the greatest, but apparently there are plans to redevelop the old industrial area as high-quality public riverfront space.
It's wil-AM-et, btw!
