There were several monuments placed along the D&RGW (C&TS) during the Kidder survey, declaring the state line by order of the US Supreme court. The easiest to find is on the east side of US285 at the state line, south of Antonito. Another is at the state line just west of the Cresco west switch, up the hillside, nearly level with the pull off area along highway 17. Follow the fence line. A third one is inside the lower loop of Whiplash. More are marked on the Valuation maps, but not (yet) verified by field trip. (One appears near Phantom Curve.)
