Bought this book at a climbing shop because at first glance it looked decent. I got home and looked at some of the peaks I have already climbed that are listed in the book. Matterhorn Peak is at least 12 miles, my computer showed the gain at closer to 5500' than the 51xx' listed. And 9 miles round trip for Mt. Ritter??? WHAT! Most accounts I have seen show it as 9 miles one way and closer to 6700' gain rather than the 4757' listed. Taking the information presented in this guide could get you in trouble. How am I supposed to believe the rest of the guide?
