Summer 2011 sees the publication of a new guidebook to the trade and sport routes of the many and varied cliffs scattered across Peak Limestone. This book takes the coverage in the Peak section of the well-received Northern Limestone Rockfax from 2004 (the Yorkshire section will be published later) and expands this with better photographic coverage, more cliffs and more routes. ''Rockfax Peak Limestone'' is the latest book to this popular area and follows on from the previous Rockfax limestone guides which have been the only real source of information for many of the crags for nearly 20 years. It will be the only single book to cover limestone for the foreseeable future.
