1985 | 2007 |
Massive recession of Vadret da Morteratsch. In 1985 the glacier front was steep and convex, which is typical for an advancing glacier. Indeed there was a small advance of 8 metres from 1984 to 85, and from 1983 till 89 the front was, in total, more or less stationary. However, since then until 2007 the total recession amounts to more than 400 metres, and the long profile of the tongue has become much flatter, typical of a receding glacier (photos J. Alean).
