The RG&SW and all its connecting spurs have been completely mapped by a person who hired a skilled guide from the Reservation. RR Grade exploring on the Reservation is considered trespass without the hiring of a guide. Not recommended as they have tribal police who use telescopic listening ears as well as telephoto scanning of the country.
The photo shows the loops on the line and the Halfway Water tank was on the right side of right loop, just below the coal mine spur.
