Crevasses should be added to mountains

I think unique world generation can make exploring your world a special experience, I think something that would add so much would be Crevasses in the mountains. They would be large ravines in the mountains made of ice, possibly even with icicles like stalactites, or thin ice, that break when jumped/stood on, making them very treacherous locations to cross, they would go extremely deep, probably to Deepslate, and that’s from the high up mountains. They would be even more difficult to deal with if something like snowstorms which would make visibility tough, were added. I think crevasses would just add so much to exploring mountains, and make them an more fun experience.
