It is interesting that this thread has come up as I was in Stevenson, Wa. this weekend on holiday. Leap day is an official holiday 3day weekend right? Anyway there is a neat museum at Stevenson on the Columbia Gorge and many local areas of interest including logging. The museum has a huge vertical mill boiler indoors along side a Corliss engine that ran a local sawmill. There are quite a few other restored pieces equipment inside such as a Caterpillar 10 tractor which is more orchard related. There is also quite a bit of SP&S memorabilia. On the grounds outside is a huge unrestored donkey engine. It was built by a company in Seattle as I recall. It may have been more of a steam powered high lead machine, as I usually think of donkey's as a bit smaller. Outside there are a number of vintage Cat's and other logging equipment. They also have an SP&S F unit sans everything in the engine compartment and an SP&S caboose.
Just up the road as you go east into Stevenson comming fron the museum on the side road which was probably the old Hwy. some private individual has a large collection of old machinery some of which appears restored such as a Cat 30 and a Cat 60. Also at this site was the front off of a mill boiler with "Oregon Lumber Company" cast in it with a date. My digital camera was unfortunately left at home. I assume this boiler front must have been from Dee.
On the subject of woods job titles, my brother in law worked in the logging industry for some years before deciding his body would last longer if he went back to college and became an accountant. His job which seemed to be in demand was "rigging slinger". When logging was down in Oregon in the 80's, he went to Alaska to work in the same job. This job is to haul the rigging up spar trees and make up the blocks with cable at the tree top level for high lead operations. A mighty tough job just hauling oneself up a tree let alone the hardware!
