Climbing Guidebook Standards…
Bern, Switzerland
The Union Internationale des Associations d’Alpinisme (UIAA) has developed proposed international standards for “guidebooks which are easy to use even for someone with little knowledge of the local language.” You can access examples of icons for use in your topos here, and a table showing the relationship between the UIAA scale of difficulty for climbs and local scales (which vary around the world), here.
A useful Climbing Dictionary is offered by rockclimbing.com here.
