Walking to the Bertol hut in the rain yesterday was a familiar feeling, but it cleared a little and we climbed the little point above the hut in the afternoon.
Happily the forecast was right and the night was properly clear, dawn bringing well-frozen, crunchy snow - something of a novelty after last week.
We made quick progress round to the Tsa with fine views and no-one else about, the 5 other teams in the hut all having set off for Zermatt on the long last day of the Haute Route.
The Tsa normal route is south facing and was completely dry, warm rock and a pleasure to climb.
