Although all the snow in Swindon had gone by Tuesday, we went up on The Ridgeway Wednesday afternoon intending to walk from Hackpen to Avebury but had to turn back due to substantial snow drifts across the path. It was very soggy and after the third or fourth instance of going knee deep through to an icy cold lake underneath enough was enough. Strangely enough after making our way back to Hackpen and setting off towards Barbury there was no such problem, other than the 'orrible Ridgeway mud which is a problem most of the year when it's wet. Sticky chalk/clay with a bit of flint which caulks on the bottom of your boot making you walk like Basil Fawlty. (Wiltshire Council renew the gravel top about once every 30 years!).
