Today Scott and myself headed up the Ben for Observatory ridge, the only ridge that I had left to do on the mountain. After a very windy walk in to the CIC hut with the wind whipping over the CMD arête and Corie Leis we headed into the shelter of the corrie. There were a good number of harder pitches up to V diff in the lower sections and then we used a combination of moving together and taking hand coils and wondering up. In the middle sections there were again another couple of harder pitches going onto the arête section right above zero gully. Further up we moved together but there were a few sneaky steps that needed to be worked out onto the summit plateau.
We were joined by the Mountain rescue helicopter dropping off a few team members and some kit. With the weather clearing up we were presented with good views out west to Skye and Rum and over the Mamores. We then rounded off the day by descending off Ledge route back to the CIC hut. In total a 9 hour day taking maximum advantage of the daylight. A good sustained ridge at the grade made a bit more interesting by the greasy nature of the rock.
