Description :
The aim of this paper is to summarize direct net balance measurements and geodetic balance measurements at South Cascade Glacier, and discuss the differences between the direct and geodetic measurements. Possible sources of mass loss that are missing from the direct method are basal melt, internal melt, and ablation on crevasse walls. Possible systematic measurement errors include under-estimation of the density of lost material, sinking stakes, or poorly represented areas.
