In contrast, this is a more current photograph (taken sometime in the 1990's) of the modern method of bringing logs in from the forest. These logs would have been cut with a machine, probably a feller-buncher, which holds the tree, cuts it off, then strips all the branches off before laying it in a pile to be loaded onto a truck by the machine in the picture below.
Another machine will unload the logs in the mill yard.
