Steile Hängegletscher Piz Palü ernähren den oberen Teil des Vadret Pers. Auf dem Gletscher verlaufen markante Mittelmoränen; unten links die Ufermoräne aus der Kleinen Eiszeit. (MH)
Looking down the narrowing tributary of Vadret Pers as it flows towards Vadret da Morteratsch in 2006. The main glacier flows from Piz Bernina from left to right in the distance. The Little Ice Age moraine is in the lower right foreground. (MH)
Telephoto view of the middle reaches of Vadret Pers from Diavolezza, showing arcuate foliation, transverse crevasses, en echelon crevasses and medial moraines. (MH)
En echelon crevasses on Vadret Pers close-up. These short crevasses form in a shear zone between the faster flowing ice in the background and slower ice in the foreground. (MH)
Close-up view of foliation on Vadret Pers, as exposed in the ablated walls of an old crevasse. (MH)

View down on the top of the icefall of Vadret Pers in misty conditions in 2006. Note how the first crevasses to form (to the right) are concave down-glacier, then become transverse in the icefall itself. (MH)
