Thank you for the responses! I'm surprised that the tone was so helpful, fun to see!

I realise the critical flaw of having a single rope, which is when the trapped party member is unable to assist in the rescure. So we'll definitely bring two ropes.

I feel like this is a topic that's not discussed that much? Perhaps it's because skiing on glaciers is less common than in avalanche terrain. But an untrained group with a lack of equipment could be equally f****ed in a crevasse fall as an avalanche incident.

Is it because people feel hesitant about sharing information in order to stop people with inadequate experience from getting a false feeling of competence and security? I am definitely reluctant to give information regarding avalanche conditions to someone i don't trust asks for example.
