Les bandes de Forbes ou ogives sont des bandes annuelles, bleues ou sombres, à la surface d'un glacier. Elles sont liées à la chute de séracs. La glace est zébrée de bandes alternativement bleutées (claire en hiver) ou grises (en été, dues aux poussières) qui se déforment progressivement en ogives ou chevrons. La chute de séracs est une condition essentielle mais toutes les chutes ne donnent pas forcément des bandes de Forbes. 1, record 1, French, - bande%20de%20Forbes
