The mean cumulative mass balance loss has been -18 m w.e, which is a minimum of 21 m of glacier thickness lost. North Cascade glacier average thickness ranges from 30-60 m. Thus, 25-40 % of the volume of these glaciers has been lost since 1984. WebThe mass balance of these glaciers has been negative, i.e. they have been shrinking overall, for the past 31 years. The cumulative loss of mass since 1976 amounts to around 20m of water equivalent. “Water equivalent” is the depth of water that we’d get on the glaciers if all the lost ice and snow were melted. holiness and obedience
