Yes, far northeastern California. Of the four photos in that post, three are of The Red River Lumber Company, though if after 1944 it would have been Fruit Growers Supply Company. Western Pacific used the three steel cars pictured on the passenger special they operated that transported TRRL/FGS loggers between Halls Flat and Westwood. These photos appear to be shot mostly in the Halls Flat area, which was site of a large logging camp and connection with a logging railroad running into the woods to the east. Incidentally, Philip Johnson shot all those photographs, he was an entomologist with the US Forest Service who spent a lot of time working in various insect inventory and control projects throughout the Pacific Northwest. He often spent months on end living in and working from remote log camps, and he’d often get rides on log trains and then send pictures back to either the company or train crews. University of Montana has part of his collection, there are a bunch of photos of various McCloud River and other operations in the CSU-Chico library and available on line through Calisphere that have been identified as his work, and I think a niece of his has a lot of his original negatives and sells prints of them on eBay, she’s also had tables at Winterail.
