Tonanzi Rock climbing 3 routes in cliff

Climbing around Cienega de Gonzalez developed over many years and was and is being carried out by many different developers. Many of them local Mexicans but also loads of foreigners that pass through, bolt and "disappear". The information about climbs in this area is thus incomplete in the sense of route names, developers, first ascensionists and sometimes even grades. Please contribute by entering your grade contributions (Edit Route, enter grade, safe) and by adding new routes and information whenever you encounter it. The climbing community will be thankful!
