These two photos from Jack Duncan seem to show Highway 40 "near Donner Summit," according to the caption. I'm having a hard time locating this particular spot. It looks much like the area between Cisco Grove and Big Bend, but the old road on the right rises much more rapidly at that location. The second photo below seems to show the same area, but check out all the traffic. If you know where this photo location is, please let us know.
