As a native of a very well known mountainous state I can say it's more than that. If you're summitting on a mountain you need to be prepared to bivouac at least one if not two nights and survive adverse weather. Even experienced hikers can find themselves trapped far from the trailhead by either weather or fire. That's not even talking about the usual bears, mountain lions (don't hike alone), or ticks (Lyme Disease is real).
