Graduação
Para classificação do grau de dificuldade de cada montanha iremos utilizar padrão alpino da UIAA – Union Internationale des Associations d´Alpinisme (UIAA Alpine Grade). É importante observar que esta é uma classificação relativa, ou seja, o grau de dificuldade em relação ao ambiente em que a escalada é realizada: altitudes elevadas, com presença de neve ou gelo e baixas temperaturas. Assim, as rotas das montanhas classificadas como F (fácil) não significam que são acessíveis sem uma preparação física e técnica adequada. São fáceis se comparadas a outras rotas de características alpinas ou de alta montanha, mas trazem riscos que não devem ser ignorados.
| OVERALL GRADE | DESCRIPTION |
|---|---|
| F Facile (Easy) | A straight forward route, possibly describing a glacier approach with simple scrambling. Any snow or ice will be of an easy angle allowing the climber to walk up it. |
| PD Peu difficile (not very hard) | Harder than routes graded F, with more complex glacier routes, harder scrambling and objective dangers. Routes may also be longer and at altitude. Snow and ice slopes of up 35-45 degrees may be encountered. |
| AD - Assez difficile (fairly hard) | More significant slopes of snow and ice will be encountered up to 40-55 degrees. Rock climbing up to grade III may also be encountered but are unlikely to be sustained |
| D - Difficile (hard) | A more serious undertaking with possibility of rock climbing at around grade IV & V and snow and ice slopes of up 50-70 degrees. |
| TD - Tres difficile (very hard) | Significant and sustained snow and ice slopes of up 65-80 degrees are likely encountered. Hard rock climbing is also a possibility at grades V - VI with some aid routes also a possibility. Routes at this grade are a serious undertaking with high levels of objective danger. |
| ED - Extremement difficile (extremely hard) | Extremely hard routes with vertical ice slopes likely and rock climbing at VI to VIII. Aid pitches are also possible with exceptional objective danger. |
| ABO - Abominablement difficile (Abominable) | Pretty self explanatory! |
