WebUpper Right Menu. Login. Help WebA glacier can be divided into two zones; the upper accumulation zone, where the snow mass accumulates and the lower ablation zone, where more glacier mass is lost, or ablated, than gained through snowfall. Ablation can occur due to melting, wind erosion and calving (National Snow and Ice Data Center, 2024). The point between the two zones where …
