Like almost all other glaciers in the Alps, and most glaciers on the globe as well, due to global warming the Gorner Glacier is a retreating glacier—and in quite a dramatic way. Its highest peak measures 4,274 meters above sea level. If they lose ice quicker than they receive their income of fresh snow, their mass begins to diminish and glaciers begin to retreat. The method is shown to give results consistent with ground-based observations for the Franz Josef and Gorner glaciers and is further applied to estimate the retreat of Viedma, a glacier with no available ground measurements. Over time, a glacier's front may naturally advance or retreat, but the new research shows that none of the 225 ocean-terminating glaciers surveyed has substantially advanced since … The glacier then moves down the Rhône valley. The outcrop to the north is rich with minerals that interact with rainwater to produce an acidic environment on rock surfaces that leads to rapid chemical weathering of rock, while the combination of minerals in the outcrop to the south produces a less acidic environment that slows weathering.
