I’m getting tired of writing, "another excellent book in an excellent series…" but that’s just the way it is. Rock Climbing Anchors: A Comprehensive Guide by Craig Luebben lives up to the high standards of Mountaineer Books Outdoor Expert Series.
There’s no way to avoid a comparison with Climbing Anchors 2nd Edition by Long and Gaines, so let me just say this: both thoroughly cover the subject, you’ll be happy with either, if you really want to know your anchors you will get both.
Leubben invented the Big Bro, writes for Climbing magazine, blah-blah-blah. More interesting is how his background in mechanical engineering (if that’s not strange enough he actually likes off-width cracks!) informs his advanced discussion of the physics of fall forces; there’s even an appendix for equations.
Equations aside, the book is extremely readable and chock full (ouch!) of excellent photos and illustrations, as well as tables and call-outs for exercises and advanced tips. Rock only, no snow or ice.
