you're climbing a real mountain, get a real camera. Seriously, the GoPro has its place, but not for quality photography of big landscapes. Denali is a big landscape, you will want to zoom and get a broad scope of focal distances. I think most Go Pro images turn out looking like junk. Spend $300 and get a solid point and shoot with at least a 5x zoom and you will be way more satisfied in the end.
