Top - This photo of Lake View Station, located within Lake View snowshed, shows a woman on this staff crane used for passing a staff to a locomotive engineer thereby controlling entry to a block - Date? Photographer? - Truckee Donner Historical Society.
 
Middle - The above photo appears at two locations on the web, each a reversed image of the other. The leftmost photo would be my best guess as to which image is correct, however, the comparison of the track curvature doesn't seem to match the bottom photo - Date? Photographer? - Truckee Donner Historical Society.
 
Bottom - This photo displays the scene properly as the Lake View station name sign is clearly readable. The staff crane looks like it is no longer in use. The track appears to be straight without any curve as per the top photo - Date? Photographer? - Truckee Donner Historical Society.
