No markings for the ROW, and no way to tell from the contour lines; they followed the contours.I found it! I used NYS LIDAR to trace it into OSM here: https://www.openstreetmap.org/way/732003601 . It's completely demolished at the Concord Resort Hotel site east of Kiamesha Lake, but is otherwise intact elsewhere.
