This photo was shot by Alfred A. Hart during the contruction of the tunnels near Donner Summit. At the top is visible a plume of steam from the engine used to hoist rock out of the vertical shaft in the middle of Tunnel 6. This is adjacent to the Sugar Bowl Academy/ASI building at the top of old Highway 40. At the bottom the China Wall is being built between Tunnel 7 and 8. To get the photo, Hart had to haul heavy camera gear to the top of the bluff above Tunnel 8.
