WI sta per Water Ice
X per indicare strutture particolarmente fragili e R per il ghiaccio sottile.
WI1: Low angle ice; no tools required.
WI2: Consistent 60º ice with possible bulges; good protection.
WI3: Sustained 70º with possible long bulges of 80º-90º; reasonable rests and good stances for placing screws.
WI4: Continuous 80º ice fairly long sections of 90º ice broken up by occasional rests.
WI5: Long and strenuous, with a ropelength of 85º-90º ice offering few good rests; or a shorter pitch of thin or bad ice with protection that?s difficult to place.
WI6: A full ropelength of near-90º ice with no rests, or a shorter pitch even more tenuous than WI 5.Highly technical.
WI7: As above, but on thin poorly bonded ice or long, overhanging poorly adhered columns. Protection is impossible or very difficult to place and of dubious quality.
WI8: Under discussion.
