This glacier exists well below the true snowline and is sustained by avalanching snow. The climatic glacier snowline (ELA) was lowered from to at glacial times. The climatic glacier snowline (ELA) was at about . The climatic glacier snowline (ELA) was lowered from the current to during glacial times. During the Ice Age, the glacier snowline was about lower than today. The snowline in the area lies at altitude at Cumbre del Laudo. The snowline was lower during the last glacial maximum, probably due to a wetter climate. This glaciation took place in correspondence to a lowering of the snowline by . The highest level below the snowline is dominated by lichen and bryophytes. In the average winter the "1,000 metre snowline" sees most of the mountains with snow. The rufous-bellied seedsnipe ranges as far up as to the snowline (5500 m). Today, the snowline data set consists of 41 years of climate data and climbing. They followed the river and reached the snowline. The current snowline (Stage 0) is nearly unchanged. This is done on the water for schools below the snowline.
