I belong to a Facebook group about north Idaho, and people post their old photos there, plus ones from some of the historical museums. I am not sure of the date for this picture, but someone said the logging truck is a C-Cab Model T; so I am guessing that the 1920's would be somewhere close to the right time period. This picture is amazing when you really look at it ! The log is HUGE, it is not even tied onto the truck in any way, just (somehow ?) laid on top of wood blocks. The whole bridge across the canyon is made of log, and even the road across the top that the truck is driving on is only logs laid side-by-side. These guys had to be not only tough as nails; but way, way brave, too ! !
