Tail trees also known as lift trees, are being used on the units I've been taking pictures of because the ground is not steep. The area was skidder/cat logged in the past down to the roads. Nobody walked it much to see if it was viable to skyline log. A judge during one of the court hearings pronounced it was to be 100% cable logged. Because the ground also "roman noses" off between the landing and tail tree, the loggers are using intermediate supports at these places--they rig a tree by the problem area (guyline it, hang a block)
and then hang a hunk of iron that supports the skyline and allows the carriage to run over it. Kind of goes KA THUNK when it runs over it. This keeps the logs from plowing a ditch when the ground changes profile. There's a lot of stress put on this tree also. So, a good hooktender will pick a nice, sound, sturdy Douglas-fir to use. Sometimes they top it, sometimes not. The same kind of tree is preferred to use for the tail tree and guylines. The yarders used here for the smaller second growth are made to be rigged up fast, usually a maximum of 4 guylines. The old growth size yarders use 6 to 8 guylines.
The crews on the thinning operations around here vary in size every day. It is a real problem finding reliable help--Gyppo logging, not big companies. They like to have 2 guys setting chokers, a hooktender to rig ahead and set chokers when he's caught up, a shovel operator, a yarder engineer and a chaser. But, I've often seen them running short with half a crew. Not a lot of production, but some. There's one operator who runs a Koller Yarder with his dad and brother. That way they know they'll show up. The two brothers do the cutting. When they have enough on the ground, the dad helps to rig up the yarder. The yarding is done with the dad as yarder engineer and one of his sons as the choker setter. The other son loads and drives their truck.
Well, the coffee's gone and I gotta go. ..later.
