Rossiter's guidebooks Boulder Climbs North and Boulder Climbs South set new standards for great topo based guidebooks, and are still used and sought after as they cover the whole Boulder area Front Range in just two volumes. These days it takes a suitcase to carry all the guidebooks for this region.
