Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry.

Review: I remember reading these as a kid and then buying all of them a few years later. The stories were great the illustrations were creepy, and like a lot of reviews, my little brother was scared of that picture in the haunted house story. well, ok it was pretty darn ugly. This is one of those books that still gives me the chills especially fro mthose pictures? oh what a warped mind that artist had but what creative drawings they are!Now, if you think the books are scary, try listening to the cassettes. i am in my twenties and the voice of the narrator and that creepy music gives me the willies. try listening to it in a room by yourself, and see how long it takes you to run for the door! The Scary Stories and More Scary Stories cassetes (i am not kidding) it is a kid's tape and that music will creep you out. listen to it! pick up the book follow along and see how long you last!

Review: It was recommended to me by someone whom I think beleives in the interdimensional and non-ET aspect of it all. I kept an open mind, but finally came to the conclusion that John Keel wrote a fradualent and contrived story, with an underlying "distracted" attitude that in reality is quite insulting to the reader. The book is probably pure fiction, and if you seek more than fiction, then it is bordering on pure trash. As an "investigator" he poorly documents his findings. Don't buy it, check it out from the library, please.
