Looks like a C.R. Lively photo. He was the agent/operator at Cumbres in the early 1900's.
This is taken in the area uphill from the present highway crossing below Coxo Siding. Most of these snowsheds were removed/burned down in the 1920's. The bigger locomotives didn't need the snowsheds and could power their way through the snow easier than the small engines.
The last snowshed on the hill was around Coxo Curve. It was torn down in 1938 or so.
Up on Windy Point where the big snowdrift forms, on the uphill side there are a couple of steel rods driven into the rock from which short lengths of steel cable hang. These cables were to hold up the snowshed that used to be there.
I always thought it would be a "fun" project to rebuild the snowshed up on Windy Point. Mostly because I thought it would be cool to blast through it with a wide open throttle. But after I had run SLRG 18 wide open through the tunnels on La Veta, I changed my mind.....
