The owl remains an iconic symbol in a region where once loggers in steel-spiked, high-topped caulk boots felled 200-year-old or even older trees and loaded them on trucks that compression-braked down twisty mountain roads to mills redolent with the smell of fresh sawdust and smoke from burning timber scraps.
