    "content": "The official Ohlone Wilderness Permit Map marks the red hikers-and-horses-only Ohlone route, numbered posts OT26 through OT35, and the Lichen Bark start area. It prints 0.91 mile from Lichen Bark to OT40; mainline distances of 0.37, 0.16, 0.22+0.21+0.35, 0.28, 0.99, 0.91, 0.52, 0.35, and 0.83 mile between OT26 and OT35; a Maggie's Half Acre parallel route of 0.05+0.84 mile between OT27 and OT29; a Stewart's Camp parallel route of 0.60+0.46+0.61+0.28 mile between OT33 and OT35; and a 0.16-mile one-way spur from OT26 to Doe Canyon Horse Camp. 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.",
