Most theories based on avalanche / snowslab / ice glide are suggesting that the event happened near the tent, and made the skiers flee to the treeline.
But what if something else made them flee the tent, and then some sort of snow glide or ice glide happened in the ravine, as the Rav4 were building a den?
I say this because of the injuries suffered by 3 of the Rav4 that could be explained by a large amount of snow hitting them. If those injuries were caused as they were still in the tent, I don't see how they could have managed to walk to the ravine.
I'd like to hear your thoughts on that. Could this ravine be abrupt enough, or deep enough to cause such an event?
