|Sort Yard Cold Deck|
A cold deck is simply a pile of logs are stored. This contrasts to a 'hot deck' which might be a small surge pile into which logs are constantly coming and going. Logging is not a 'just in time' process in which logs are made the day before they are sawed. Rather logs are harvested when weather and schedules permit and then they are piled up. Often the piles are at the mill where the logs are awaiting sawing, or an export dock where they are awaiting a ship, but the cold deck as here can be out in the woods where the loggers have gotten ahead of the trucker and the logs are simply stored until the trucking can be accomplished.
Sometimes on the way to lumber, logs can spend some more time in sort yards awaiting shipment to their ultimate processing point. Those piles are usually larger.
