Normal route from Arolla with bivy at Plans de Bertol. Took the dertour via Cab. Bertol when ascending. Transition from Glacier Mont Mine to Glacier de'l Aiguille is anardous pile of rubbish.
Finally a nice and exposed, albeit short climb; several bolts plus three stances, of whom the first may be skipped (50m rope, easy terrain). Two rappels of 50m straight down the east face (not the north arete as mentioned in the guidebook).
Backwards we cut short via Col de la Tsa, where a steep section plus rimayamay pose difficulties when anscending (rappel). For ascending, on could scramble through the rocks on the north side of the col.
Nice climbt after the Dent du Tsalion Date Climbed: Jul 21, 2009
It was a nice climb with good bolts and abseil anchors. We climbed the Tsa after we did the Dent du Tsalion west ridge. Descent via the glacier du Bertol was still possible but it still is a long and tedious decent back to Arolla.
Starting from arolla we went to cab. de tsa and climbed the west ridge of the dent du tsailon. Once up there we went up the aiguille de la tsa. In descent we took the first col on the right going towards the cab. de bertol. Descents, I hate them, except of course the view to les bouquetins.
