I can remember when the Richfield letters were still on this tower, and the station was still in use. In more recent times it's been a real estate office, and then a home. Doesn't look like anyone's using it now. This is on the outskirts of Mt Shasta City.
The MS on the tower IDs it as Mount Shasta; used to be lots of these navigation beacons around the area when I was a kid.
I took these pics as I want to build a model of it when I build my train layout.
