At the head of the Lares valley, under the ridge Carè Alto – Corno di Cavento – Crozzon di Lares, the Lares glacier is the third of the Adamello (4.17 km2). Fed by snowfall, it ended up in Lake Lares until the 1990s. Today it is completely free of ice and icebergs.
The surface of the Lares glacier amounted to 484 Ha in 2003 and was more than halved compared to Julius Payer estimates of the mid-1800s, which gave it an area of about 1150 Ha. In 1925 the area had shrunk to 635 Ha, while in 1960 it was about 60 Ha. It occupies a rather regular slope and in some sectors its surface is crossed by deep crevasses, like those downstream of the Corno di Cavento. Until a few years ago, the southern portion connected with the Niscli Glacier through a steep, frozen, now completely interrupted slide. According to the estimates of the SAT glaciological committee, the glacier lost between 1991 and 1997 a volume of almost 27 million cubic meters equal to a loss of average thickness of more than 5 meters. The front retreated around 110 m in 11 years (1993-2005).
Today the Trentino glaciers cover an area of about 30 km2 and are located in the main mountain ranges, first of all the Adamello – Presanella massif which alone hosts 48 glaciers.
Although at first glance it appears to be immobilized by frost, the glacial landscape is in continuous movement and constant evolution. Even more so today, due to the climatic changes that triggered the inexorable and very rapid withdrawal of the glacial front.
The glacial extension is everywhere in a significant decrease. Some of the largest glaciers have lost in just over 40 years up to 42% of the surface, for others the reductions have been smaller, as for the Adamello Glacier.
Studies on the Adamello glaciers have developed with a certain systematicity since the 1920s, but as early as 1865 some of them were accurately represented in a detailed paper made by Payer, the first conqueror of Cima Adamello, as well as a careful glaciological detector.
