Here's a picture of Mt. Washington I took from Mt. Clay during my second climb up The Rockpile back in July 1963.
As you can see, the summit has changed a bit since then. The large building over near the homestretch is (IIRC) the Air Force icing study lab. A close examination reveals two cog railway trains just above the Great Gulf.
Sorry it's B&W. I was doing my own processing back then and B&W was all I could afford.
I'll add more later.
