This is the image (DPL):


I'm not sure where this is. If it's looking out of the East Portal, the track curves the correct way, but the hillside is on the wrong side of the track. There isn't enough scenery around (except for snow) to get a good location. If it's labelled correctly, it is probably taken from inside one snowshed on the approach to the tunnel, looking at another.

For anyone with Red-Cyan stereo glasses, here's a 3-D anaglyph:

Your second sentence is right.Look at the embankment that can be seen through the snowshed.For this thread I was calling attention to the heavy timbering of the snow fence between the two sheds.

[Todd Hackett]

I'm not sure those timbers are a snow fence. Snow fences create a low pressure and wind patterns on their down wind side that causes drifts to form. When they are parallel to the road or track, they are placed far enough away that the drift will form between the fence and the road/track. Placing them this close will cause the snow to drift on the track if wind blows one way, or prevent drifts in a place where they wouldn't be a problem if if blows the other way.

I would say those poles are bracing the squared timbers for the erection of more snowshed, no other explanation that I could figure.  Perhaps the intervening section was burned, collapsed or swept away.
