The monument is adjacent to where Wisconsin Avenue crosses over the C&O Canal in Georgetown. It is effectively a zero mile marker, although not precisely, as the canal continues a few hundred yards past the marker to empty into Rock Creek. It commemorates the construction of the canal. I caught it right at “magic hour” when the sky is just dark enough that it matches the ambient street light, but is not so dark as to lose all detail and color. Here it has a wonderful indigo glow. And no, no flash was used in the making of this shot- this was purely ambient light from the street lamps and the sky.
