Mapped record is not an itinerary
Forest Service centerline mileage describes a managed trail record. It may omit an approach, summit route, connector, return leg, or current detour.
Sources before scores.
The catalog currently joins 164 official trail records, 4,279 named places and facilities, and 566 miles of Forest Service centerline. Harvested Aug 16, 2026.
Difficulty has dimensions
Trail class is a maintenance standard, not a hiking rating. Edited guides keep effort, footing, navigation, altitude, and commitment separate.
Comparison stays separate
Utah and OpenStreetMap data can expose missing names or geometry. They do not silently overwrite the Forest Service record or establish legal use.
Unknown is a real state
A missing ford report, incomplete route definition, or unavailable alert feed is labeled instead of converted into confidence.
Downloads preserve the source line
Every official catalog page can export its exact harvested TrailNFS geometry as GPX. A saved trail is local browser state, not an offline map package.
