Hello,
Here's a couple good links to check out before heading out ski touring this coming winter.
The Canadian Avalanche Centre has put together a good amount of resources for pre trip planning, human factors and also a basic online course. Worth a look!

Maybe less of an issue in the Alps but here's also good link for Tree Wells for people in your group that might not have skied in the trees before.

Friends sent me some photos of snow in the mountains back home and it got me thinking Skiing, can't wait!
All the Best,
Owen
