The arch at Valley Forge
The memorial arch at Valley Forge, PA. The area is in the flight path of a major airport, making contrails unavoidable (the curved vapor trail on the upper left is one).
The arch dates to 1917 and is described in detail at this national park page:
www.nps.gov/archive/vafo/MONUMENT/vfmon08.html
See the sky through the arch:
