Galmilücke: Descent to Münster via Blaggibärg and Minstigertal
In general, see swisstopo trace and GPS. Reach the Galmilicke from the W over the Galmigletscher, e.g. from the Oberaarjochhütte (200m+) or Finsteraarhornhütte (600m+). At the Galmilicke, do a 15m rappel on the E-side to reach the Minstigergletscher. The rappel can be circumvented by declimbing a snow ramp a few meters higher to the S if snow coverage allows. Ski down the Minstigergletscher until its end at 2600m, traverse towards SE to reach the entry of the Blaggibärg-couloir (2500m), ski it down and follow the Minstigertal out. At the end, one typically follows a forest trail on the true right-side of the valley to reach Münster.
Varied descent option to leave the Fiescher-/Oberaararea to the Goms, less popular(?) alternative to the Bächital.
Mainly E-oriented, thus transforms rapidly in warm spring conditions. The Minstigertal stays longer snow-filled in spring than its exposition might suggest.
