Don't forget Mossyrock, downstream from Morton, well named!
And don't forget the research into the aftermath of St Helens if you pick that area. I can cut alder firewood now and still find ash in notches of trees 35 years later!
Note: sure others have thought this, and no disrespect, but if I were single, would not mind showing you around the woods ?
I'm not single, but I'd show ya around the woods, I'm just not part of a yarder crew, just a dumb gyppo with no money to hire help....
few machine brands to either google image search, or youtube...
Timberjack skidders
John Deere skidders loaders etc
Caterpillar et al
Garrett/Can-Car/TreeFarmer/Franklin all the same skidder
Skagit yarders, yoders, winches, towers (pronounced ska-jit not sure if its native or just someone with no teeth?)
Washington yarders
Madill yarders, loaders
Berger yarders
Tigercat all sorts of forestry stuff... mostly modern grapple stuff
Christi (y?) yarders and a bitchin carriage

KMC some bitchin tracked skidders that look a little like tanks with blades on the front... just a nightmare for maintenance

Some where's in Arboristsite, there is a glossary of logging terms/slang, probably in the forestry and logging forum as well... someone will put up a link I'm sure.
