geography
course
The Sefinen Lütschine rises from a small firn at around 1980 m above sea level. M. on the eastern slope of the Jegihoren .
At Firten flows at about 1420 m above sea level. M. the similarly large Sefibach from the left to. It continues through the Sefinental to 1200 m above sea level from the left . M. the Schiltbach flows into. Then it moves on through the valley below Gimmelwald .
