Rich- I think the wye that was referred to is the one up by the mine. It's about a mile down grade from the end of track. We drove right by it and didn't see it although it is clearly visible in the aerial photo if you follow the line out of Villa Grove. Just beyond the wye on the branch the foundations for a section house are also visible. Earl and I surmised there was a water tank at the section house as there seemed to be more water there than at the mine itself (I can't recall if we also found tank footings).
