KELSO, Wash. – During timber's heyday, it was common to see tugboats pulling huge rafts of logs to area mills. In the process, many valuable old-growth trees sank to the bottom of Northwest rivers and lakes. That's given rise to different breed of logger. A few enterprising souls have sought to take advantage of the underwater hidden forest. But Washington State has moved decisively to shut down underwater timber salvage operations. That's effectively sunk the business in Oregon too.
