Glaciers
Notable glaciated areas in this range are: Leon Huaccanan-Azuljanka, which is a plateau of 10 km. long and 2½ km. wide that rises eastward, to a steep cliff in its eastern margin; a tiny ice plateau at the union of the Yarupac-Torre de Cristal ridges; and finally mount Santa Rosa which has the most of the remaining glacier ice. Permanent snow begins at about 5000m in the northern and central parts of the range.
Environmental issues
This mountain range has a bad conservation status because of mining activity in the area and the ongoing glacier retreat due to climate change. Explosions and pollution of lakes are important disturbances to the local ecosystem caused by mining activity. There are also abandoned facilities of other mining companies in the area.
