As its name suggests, during the Little Ice Age, the Añisclo Northeast Glacier was located to the northeast of this peak. Its area was estimated at 10.5 hectares, notable for its longitudinal structure of 1,180 metres, then the 11th longest in the Pyrenees. Today, a small mountain lake is flanked by the frontal moraine. Until the early 1990s, it maintained a well-defined Helero structure. In 2000, after splitting, it was considered practically extinct. Since then, a persistent snowfield has hidden it for almost a quarter of a century. Two fragments with a combined area of 0.4 hectares of deteriorated glacial ice reappeared in 2023, confirming its existence.
