Source dates, exact IDs, transformations and disagreements: catalogue.json and each
route JSON/GeoJSON, methods.html, plus retained lane source audit and receipts.
This dated atlas is an educational overview, not navigation, current opening, safety,
accessibility, water availability or a ground-level survey. No NPS endorsement is implied.
Distances are horizontal mapped lengths. Derived ascent is method-dependent.

The offline ZIP contains field-guide.html, guide.css, methods, this notice, the
catalogue and all route GeoJSON/profile CSV exports. Extract them together and open
field-guide.html. Diagrams, descriptions and exports need no network; external
primary-source links require a connection to their origin.
