The ELA can rarely be observed as a line at the same elevation across the entire width of the glacier due to local topographic and climatic variations in accumulation and ablation ... Thus, the ELA is the average altitude of the equilibrium line.  3, record 1, English, - equilibrium%20line%20altitude

... accumulation and ablation don’t occur equally over the whole surface of the glacier. Ablation dominates the snout of the glacier, where the climate is warmer and iceberg calving can happen. Accumulation therefore dominates the upper part of the glacier, where temperature is low and precipitation is suitable for snowfall... So a glacier can be divided into two areas, an accumulation zone and an ablation zone. The line separating the two is called the equilibrium line...  6, record 2, English, - equilibrium%20line%20of%20glacier

La limite entre ces deux zones [accumulation et ablation] est dénommée ligne d'équilibre d'un glacier. Le bilan de masse annuel est nul (autant d'accumulation que de fonte). L'altitude de la ligne d'équilibre varie évidemment d'une année à l'autre (parfois de plusieurs centaines de mètres) notamment en fonction de deux paramètres climatiques : a) La quantité de chutes de neige totale tombée au cours de l'année, en particulier durant la saison hivernale, détermine l'accumulation. b) Les températures estivales régissent la fonte (ablation) durant la belle saison.  6, record 2, French, - ligne%20d%27%C3%A9quilibre%20glaciaire

En aval de la zone d'accumulation se trouve une partie du glacier où l'ablation l'emporte sur les précipitations : c'est la «zone d'ablation».
