The lines are the Bureau of Land Management's National Trails Managed for Public layer (public domain), read 2026-10-16 and simplified for the map; the length is the Bureau's GIS mileage where it gives one, else the line's, and the surface, route use class, trail system, designation and OHV limit are the Bureau's own entries as observed and planned. The layer names no trail id, so a trail is its segments of one name in one trail system, split where they lie apart. The trailheads and the points along the way are the Bureau's recreation points, and a write-up its own text on the trailhead. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the Bureau's own site before you go.
