The high-lead cold deck is a physically curious device that had a profound impact on the fortunes of early-twentieth-century Pacific Rim lumber companies. At the apex of a single-spar tree ran a series of cables that were anchored to stumps, the whole resembling the skeletal frame of a big top. But there the resemblance stopped. A mainline, attached to the steam-powered skidder at the base, looped through a block atop the tree, then through others around the perimeter of the site, and finally attached to a haulback line, created a complex system that enabled loggers to pull timber partly suspended in the air over long stretches of ground. This technological innovation sped up production, lowered costs, and reduced damage, savings that accelerated the clear-cutting of vast tracts along the west coasts of Canada and the United States. |
