Snowsheds at Donner Summit
Does anyone know when the Central Pacific Railroad snowsheds were constructed on the east side of Summit Tunnel? Before or after tracks were laid? Timothy O'Sullivan photographed the sheds, but its not clear whether he did it in 1867 or 1868, nor when within whatever year. I'd appreciate any documentation on when the sheds were actually built.
I note I have three O'Sullivan photos of the CPRR at Summit – two which show sheds, and one which might show graded right-of-way without tracks. It's possible that O'Sullivan made a couple of trips to Summit – perhaps one in 1867 before track was laid, and another in later 1868. That is all speculation on my part.
Many thanks.
