Lake Sant’Agostino

The lake (500 metres long, 100 metres wide and with a maximum depth of 6 metres) is situated in a side valley running parallel to the main valley.

This particular landform is attributable to the fact that, during the peak of glacial expansion, the valley was occupied by a minor glacier tongue, which subsequently evolved (during a phase of glacial retreat) into aspillway channel, that is, the area through which meltwater was channelled.

The very spot where the Chapel of St Augustine stands bears witness to the glacier’s passage through this valley: it is, in fact, a moraine, a typical form of glacial erosion, on which one can see the parallel grooves running alongside the valley, left by the passage of the glacier and its debris.
