A survival book that isn't depressing?

I love love love books centered around wilderness survival stories but the vast majority tend to be pretty depressing in general. I'm fine with dark parts/gritty stories but does anyone have any recommendations for stories that don't have an overall depressing vibe? For reference I like books like The Great Alone by Kristin Hannah even though it has darker themes because it's not all doom and gloom. Thanks in advance :)
