Day 1 (4.2.2015) will mainly be dedicated to the presentation of the scientific outcomes of the TEMPS project. All talks will be held in English.

Day 2 (5.2.2015) will focus on practical issues related to changing permafrost conditions in the Alps and is also especially addressed to all practitioners interested in permafrost-related topics! Talks will be held either in French or German.

6/7 February 2015


Two-day skitouring excursion to the Becs-de-Bosson and Tsavolires rock glaciers (permafrost kinematics monitoring sites) in the upper Réchy valley with overnight stay in the Becs-de-Bosson alpine hut at almost 3000 m altitude.

Day 1: Access to the area (by bus, cable car, and ski lift), skitouring visit of the investigation sites, and ascent to the hut.
Day 2: Skitouring excursion with a long final downhill! The excursion will end in Sion sometime in the early afternoon.
(Programme is subject to changes depending on weather and snow conditions.)

150 CHF (including transportation from and to Sion, cable-car and lift tickets, accommodation, dinner and breakfast, mountain guide)

Specific skills and equipment
• Complete skitouring equipment (can be rented locally).
• Acceptable skiing skills.
• Enough fitness for a three- to five-hour skitour on both days.
