Re: SN picture

Too bad our source of ready answers is gone and a call to Allen would have sorted it all out, with a few extra details thrown in. In addition, there was the Mears-Wilfley mill in that stretch of canyon, and we do have a good photo of that one. I'm sure when I can get to a copy of Allen's Many More Mountains and check his maps, it will all become clear. The Iowa-Tiger mill was halfway up Arrastra Gulch, with the terminal for the tram for concentrates on the SN. Lower down from this photo we're talking about, and on the other side of the river, was the Silver Lake Mill. The Silver Lake and Iowa-Tiger were owned by the Stoiber brothers, but were operated separately. And we need to contend with the Contention. Whoever wrote the library's captions was groping for the right description and terminology. The shots inside the Alamosa shop (not roundhouse) are nice studies--the engines were always separated from the tender when in this structure--the tracks weren't long enough.
In answer to Dave's question, that indeed looks like a track with a car on it above the terminal building. Everything is currently covered in 8 inches of new snow, or else I'd go up there and try to place all this. I sure didn't recall that picture, and I worked on Sloane's book for Sundance, but that was some time in the distant past.
