If a glacier is in equilibrium, where ablation is equal to the accumulation, what occurs in the terminus or 'snout'

The answer is : neither erosion nor deposition occurs.
If a glacier is in equilibrium, where ablation is equal to the accumulation,  either erosion nor deposition occurs in the terminus or 'snout'.  It stops depositing rocks, the snow would stop falling at the terminu, the temperature would rise, It is neither advancing nor retreating anymore.
