Questions that don't deserve their own thread.

How do I git gud at mountaineering? I have a long term goal of climbing Denali, solo if possible. I did King's peak this year in Utah by myself. I am aware that there is a huge difference in the challenge. I want to work my way up toward taller and more challenging mountains, but I don't want to get eaten by a crevasse our get stuck trying descend a cliff.

What skills and gear do I need? What mountains should I practice on?
