I worked for First Choice Ski in Alpe d’Huez in 96/97, and my job title was Ski Explorer, which was half Ski guiding, half Ski Tech, as they had their own hire pool.
We were issued with full goretex uniforms in Company Colours (blue, turqoise and Pink) but were told at the time not to wear uniform when guiding as people were starting to get arrested at that point.
We had a good relationship withe ESF guys, as we put a lot of ski school trade their way, as we did a lot of school groups. We also did torchlit descents from a mountain restaurant, and we needed to have 1 ESF guide for every 10 people. The way the guys explained it was that they felt that to be safe in the mountains, you needed to have lived there and be able to read the conditions etc. I could see the point of some of what they were saying, and although we did a weeks training with an English ski school from Courchevel teaching us about keeping safe on the mountain etc., I can see that we were still very inexperienced.
I suppose that the mountains are more dangerous places in the winter, as the snow and freezing conditions bring their own risks, which need to be understood.
