South River Lumber Company. It followed Irish Creek up the valley from Cornwall. Not a whole lot left. There is a cab from Climax, or as they called it a Dinky, #5 in Cornwall. I know of a person that owns one of the set-off houses that were moved from camp to camp on the train. There are quite a few company building left in Cornwall, but only foundations of the mill. The grade is very hard to trace as hurricane Camille in 1969 caused much destruction on Irish Creek and changed the way the creek flowed.
I have reports of some mildly interesting stuff left in the woods, but nothing as large as a car or locomotive! I've nver found anything larger than a tie.
