Glaciers, Snow, Rock, and Mountains


Snow forms into fields of snow. If they persist and flow, then they are glaciers.
Note the pile of rock along the side of the Gamchiglacier, below, a lateral moraine.

The glacier is also covered with rock and debris, so it is hard to tell the difference between the glacier, talus/loose rock, and the mountain.
The Gamchiglacier looks like a dying ice field. In fact, it has receded a lot and is much smaller than shown on maps 50 or even 20 years ago.
