Breithorn central forn the Breithorn window

from the top of the Breithorn E to reach the ridge again you should descend about 60 meters. look for the two rope-rings connection to repell down
Then you can see the Breithorn Central ridge. Lower the IV UIAA step that you can avoid on th eleft side, then the other two steps of III-UIAA

Very snowy that day

PS: in case you are two climbers, I wormly racomand to bring with you 2 ropes of 50 meters instead than 1 even of 60m
