Ég er glænýr í ísklifrinu og hef verið að reyna að átta mig á þessum gráðum. Ég endaði á Wikipedia og fann eitthvað sem er notað í Kanada sem ég vonaði að sé sambærilegt við það sem menn eru að nota hérna heima.
WI3 – generally sustained in the 60-70 degree range with occasional near-vertical steps up to 4 metres (Cascade Waterfall, Banff; This House of Sky, Ghost River)
WI4 – near-vertical steps of up to 10 metres, generally sustained climbing requiring placing protection screws from strenuous stances (Professor’s Falls, Banff; Weeping Wall Left, Icefields Parkway, Banff; Silk Tassle, Yoho; Moonlight & Snowline, Kananskis)
WI4+ – highly technical WI4, notoriously as “hard” as WI5 or even WI6! (Wicked Wanda, Ghost River)
WI5 – near-vertical or vertical steps of up to 20 metres, sustained climbing requiring placing multiple protection screws from strenuous stances with few good rests (Carlsberg Column, Field; The Sorcerer, Ghost River; Bourgeau Left Hand, Banff)
WI5+ – highly technical WI5, often “harder” than WI6 (Oh le Tabernac, Icefield Parkway; Hydrophobia, Ghost River; Sacre Bleu, Banff)
WI6 – vertical climbing for the entire pitch (e.g. 30-60 metres) with no rests. Requires excellent technique and/or a high level of fitness (The Terminator, Banff; Nemesis, Kootenay Park; Whiteman Falls, Kananaskis Country; Riptide, Banff)
WI6+ – vertical or overhanging with no rests, and highly technical WI6 (French Maid, Yoho; French Reality, Kootenay Park)
Er þetta þær gráður sem er verið að nota?
