Research order
- Deepen mountains with existing source-linked routes: clarify starts, timing scope, ascent versus descent, original grading systems and restrictions.
- Review earlier route summaries against route-specific sources.
- Expand to additional mountains through alpine clubs, park authorities, huts and local guide associations.
Historical references establish records, not present-day protection, glacier geometry or access. Hut seasons and guided programmes are labelled as such. Contradictory or ambiguous figures remain open.
