A Crag Guide gives an extensive view of all sub areas and climbs at a point in the index. It shows a snapshot of the index heirachy, up to 300 climbs (or areas) on a single web page. It shows selected comments climbers have made on a recently submitted ascent.

At a minor crag level this should be suitable for printing and taking with you on a climbing trip as an adjunct to your guidebook.
