The map places water and restrooms at Lichen Bark and shows camp/facility access on the alternate routes. Distances are transcribed from printed tick labels; sums are derived and do not replace the printed components. A second map-faithful pass preserves all 39 individual mileage labels printed on the red official mainline outside the detailed OT26-OT35 slice, ordered from Stanford Avenue toward Lichen Bark. Each printed value is now assigned to an atomic leg bounded by a numbered post or an explicit intermediate mileage-tick node; two mapped consecutive-post connectors have no printed distance.",
