An Casteal and lots of snow! 4th November 2012.

The weather forecast looked promising; light winds, little cloud, great views etc, but it didn't quite turn out that way. Although there was just enough visiblity, we had to check and double check our bearings to make sure we were still on the high ground heading up Sron Garbh and onto Twistin Hill. We were the first up the hill until two groups of two followed us to a point where I felt we should bear left onto higher ground. Annoyingly, my compass had developed an air bubble in it so I wasn't happy about it's accuracy. I asked the other groups to double check my bearings and was keen to see if they would show willing to map read in front of me. One of the guys did, and confirmed what I thought, so we headed left and back onto high ground. I don't know if they would've kept following our tracks without question? 

   

The route description mentions a "large cleft in the track", which you cross with a few rocky steps (in summer), but the "cleft" was now full of deep powder, and as the snow (much more than we had expected to see) was unconsolidated it would be tricky to down climb and then back up. Plus I had no idea how deep the snow was at the bottom. Consesus was to by pass it on the right and regain the ridge. The summit of An Casteal was disappointing, only because of the low cloud which only briefly gave way to a limited view of our surroundings. It was quite chilly in the wind, so we went a little further south over the summit to find shelter and a spot for lunch. The two groups in front seemed to head for Beinn a' Chroin.

A brief view of our route back via the ridge over Stob Glas.

We found a nice sheltered scoop round the back of the summit for lunch. Note the ice axe. Not strictly necessary but they came in handy now and then. (note also crampons not used).    

Another fleeting glimpse of the way back. It was quite hard going though, through lots of deep, soft snow which Lorna found hard on her ankle. It was fine on the wind scoured ground, but inbetween there were deep drifts which were pretty tiring.  

As time was getting on we opted to make a descent into the coire and follow the stream to the river Falloch and take the road back to the layby where we were parked (a few miles south west of Crianlarich on the A 82). We thought we had taken too long due to the snow conditions, yet we never saw the other parties making their return from Beinn a' Chroin. Maybe they returned the way the came? However back at the layby there were several cars still there and it was now very dark! Hopefully they had headtorches and were ok?!
