Most likely cables used for hauling cut trees from where er were cut to where they were processed to be trucked or trained out of the forest. They might also be broken cables that they use for strapping the trees down on the logging trucks.
So what are the rusty cables poking through ground around the area? We’ve got some in our crawl space, I see them in SPI land, I see them at Lake Alpine. They are 1-2 inches in diameter, a twisted rope of metal cable. Anyone know their origin?
