Jim,
your #69 picture was taken at Fall River with the Scrap train. Great view for me, note the Mill visible behind the Headlight. This could be the Donaldson since the upper structure fits more with the Sanborn map.
Edit: Wrong conclusion. The Mill is the Hoosac and photo is taken at the outlet of Trail Creek looking up Clear Creek. This same picture is on pg80 of Mal Ferrell's C&S NG; attributed to Laurie Brown and captioned as "switching at Black Hawk".I find it a great pity that these photographers that covered the scrapping kept on taking mindless 3/4 roster shots of the same motive power time and time again. I often think they should have just stepped to the side and added in that interesting Mine or Mill.
