PizolgletscherLocation: 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). | |||

Pizolgletscher on 13. September 2006 from the north. Distinct firn stratigraphy is evident. Summit of Pizol top right, 2844.0m. Photo M. Huss. | 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. | Measuring firn densities in a snow pit. Photo M. Huss, 2. April 2007. | 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). |
