Bagby Hot Springs were "discovered" by Robert Bagby in 1880, and in 1913 the forest service built the guard station for the fire crews. I think the old log cabin nearest the springs dates to that era. The cabin up on the hill above the river is newer (50s-60s?). It had electricity, running water, and propane appliances. I think Job Corps crews built the bathhouses in the late 80s and they are showing their age. That was almost 40 years ago and the building the private cedar tubs are in has been condemed due to the structure rotting away. There are still a couple big tubs the are ok to use. There is a fee to soak but not to hike, and it can be busy.
I love the history here and have searched out a few old mines related to Bagby. One is at Pansy lake, and one in the Motherlode Creek Valley a few miles to the Southeast. There is even a filled in tunnel below the Bull of the Woods Lookout attribuited to him that served as a water source for the lookout. He's buried in Molalla Memorial Cemetery. https://www.findagrave.com/memorial/142545205/robert-w-bagby
Cache is at the top of the hill just before the bathhouse comes into view, about 1.5 miles in. Left side (going in), I only had 65 feet accuracy, so if you see the bathhouse, you went too far.
