Sadly, when you fly into a mountain in poor weather, as reportedly happened here, what type of landing gear you have becomes irrelevant.
Is very true. Though add to that thinking, that when flying floats in a water environment, you have many more landing opportunities, either forced, or precautionary. There have been a couple of occasions while flying floats in "rough" terrain, and deteriorating weather, I have picked a body of water, and landed. When things cleared, I took off, and continued. I find it much more comforting to fly a seaplane over forest/rocky areas/water, than a land plane...
