Location: 748.600 / 203.000; length 1973 (from Swiss glacier inventory): 600 metres, 2003 (based on topographic map 1:25'000): 360 metres; orientation: north; surface area 1973 (from Swiss glacier inventory): 0.21 km2, 2003 (based on topographic map 1:25'000): 0.09 km2.
Pizolgletscher is a small cirque glacier which will completely disappear in the near future. Annual variations of the snout positions are measured (=> Schweizerisches Gletschermessnetz) and mass balance measurements have been undertaken in the last few years (=> Matthias Huss, VAW, ETHZ, personal communication).

View from Pizolgletscher towards Wildsee. Near backpack: ablation stakes (ablation from 13.9.2006 to 3.9.2007 was 3.2 metres). Photo M. Huss.

The snow depth on Pizolgletscher was about 3 metres in April 2007. Photo M. Huss, 2. April 2007.
Siegfriedkarte, 1889 (original scale 1:50'000, grid width 2km). Blue contours: snow and ice. Light orange overlay: extent of glacier in 1970; darker orange: 2003.
Tele photo view from Schwarzplangg, 2.5 km to the north, 16. Oktober 2007. Note climbers and tracks in the fresh snow.
Overview from Wildseeluggen, 16. Oktober 2007: during the Little Ice Age Pizolgletscher reached about as far as the lowest snowpatches visible in the photo.
Arête leading from the north to Pizol summit (Graue Hörner). Intensive weathering has lead to the formation of a small rock window (centre right).
NW of Wildseeluggen on a riegel which dams Wildsee. Note roche moutonnée in the foreground (ice flow was from left to right).
Tele photo view towards Glärnisch (right summit: Vrenelisgärtli, 2903.9m) with small cirque glacier Guppenfirn.
Fisheye lens photo of the cirque containing Pizolgletscher and Wildsee. Angular blocks from a landslide in the foreground.
Tele photo view of Piz Sardona (3055.8m) with small Sardonagletscher on the lower left.
View from the riegel which dams Wildsee towards NNW: Schottensee is another lake, further down, which is dammed by another riegel; prominent mountain chain of the Churfirsten in the background (compare next photo).
Tele view of three summits of the Churfirsten, from left to right: Frümsel (2267m, Brisi, 2279m und Zuestoll, 2235m). Gaps between them are cirques formed during the Pleistocene period.
At Schottensee, looking towards the west. The round roches moutonnées behind the lake contrast with the angular forms of the arête on the horizon.
A small spring on the bottom of Schottensees produces a crater-like depression in loose sediments (diameter a few tens of cms).
In another cirque north of Schwarze Hörner is Schwarzsee. Far left: Silvretta mountains with several small valley glacierss (see next photo).
Tele photo view of glaciers in the Silvretta mountains; from left to right: Klostertaler Gletscher, Silvrettagletscher (convex surface), Chammgletscher (narrow) and Verstanclagletscher (mostly in the shade).
View from Baseggla to Baschalvasee and the Rhine valley of canton St. Gallen. The nearest towns are, from left to right: Sargans, Wangs (partially hidden) and Vilters.
The cairn marks the location where the ice-age Rhine glacier split into two arms, one flowing towards the north towards Bodenseee and southern Germany (top) and another, smaller one towards Walensee (left, outside the photo).
