Here are a couple of photos of my water bottle that I took to Tignes. I have posted them to demonstrate what happens when you leave a full bottle of water in the car overnight and the temperature drops to -20 degrees centigrade. In the close up, you can just see the ice coming out through the crack. This is a metal Sigg bottle by the way - the sort I thought was virtually indestructible.
Back in Arinsal, conditions on the mountain are already better than most of last season. We have been skiing powder all day, and despite a bit of wind last night, most of the snow has stuck and we seem to have a pretty good base for the time of year.
