I watched a documentary about Everest a long time ago and it was really interesting just how intense it is to get to the top. I wasn't sure if this was going to be a fiction or nonfiction book from the title. I'm guessing they never found the camera?
Yes, this was nonfiction. If you liked the survival story genre and were interested in reading a book about Everest then I would recommend "into thin air" by Jon Krakaur. That's a really interesting book about the 1996 disaster where I think 11 people (or so) died on the mountain. This book was not nearly as interesting as that one.

You're correct. They did not find the camera
I'd have to imagine it's hard. I heard that if you die, they basically just leave you there because it's too much work and risks too many lives trying to get you back down.
Yes. That's exactly it. Too difficult and too much of a risk to others to remove the body so they typically remain.
