Descending Roteck - and the cloud base is descending with me

Just over an hour ago I was on the summit of Roteck, but after a fast descent I'm back down in the Lafais valley, on a hiking trail. On the summit, I had sunshine, but a bank of clouds was hugging the north side, and there were clouds on the south as well. Although not as fast as me, they seem to have come down as well. 4 August 2012.
