Ross,
After searching my photographic albums I came across this photo of the section houses on Marshall Pass. It was taken in July 1975 with a Kodac 110 Instamatic so not the best quality. My wife and I we driving an Oldsmobile Cutlass across the pass heading west when we came across these buildings on the right hand side just east of the former snowsheds.
Hope this is of help to you. I wish now that I had taken more of the site.
Larry
