Assuming that youre asking about avalanche terrain:
Flat.
Grab Bruce Trempers Staying Alive in Avalanche Terrain. Read it along with the 15 year old. Talk about whats in it together. By the time youre done, youll know enough to modify "Flat" into something more interesting.
Other texts will suffice, but SAIAT is modern and readable. Taking an Avy 1 course together or, as a start, attending an avalanche awareness seminar theyre usually free and offered by outdoor retailers or community service organizations.
