After much reading it seems that backcountry alpine skiers, snowmobilers, and snowshowers always have avalanche gear when going into the backcountry. I haven't seen anything about cross country skiers bringing avalanche gear when skiing in the backcountry. Is it because it is thought that cross country skiers tend to ski across shallower slopes? If so, what is the degree of slope below which a cross country skier doesn't need avalanche gear/training?
On the one hand I can picture being admonished for not having gear/training for cross country in the backcountry. On the other hand I can picture being spoken down to about having the gear for no apparent reason.
I was actually surprised about how my Google skills were useless when it came to searching for beacon and cross country skiing together.
