I've encountered several inaccuracies in the second edition of this book. We recently hiked Lost Cabin-Harney Peak Loop and we were expecting to hike the listed distance of 8.6 miles but the actual distance is at least 12 miles and our GPS logged 14 miles. In addition, this hike's trail contact phone number for the Black Hills National Forest Supervisor's Office is incorrect as is the phone number for the Black Hills National Forest Visitor's Center in the appendix. Of the three hikes we have done we have found inaccurate information on all of them. The directions for Crow peak did not give adequate directions from the Interstate 90 exit, for Bear Butte the book lacked current fee information. Many of the hikes do not have their elevation gain listed. This book offers a nice overall listing of hikes in different areas of the Black Hills however the book's inaccuracies and lack of useful features such as an index, hike elevation profiles, and detailed maps that include all the features mentioned in the text make it, in my opinion, less useful than I would have expected.
