A Pattern Language is a ground breaking book. On the surface, it is a contrarian approach to architecture. On a deeper level, it is a philosophical outlook on life.
One tenant of the book is the value of selecting language units for a project. In architecture, those units could describe lots, buildings, or windows. The selection of language units can apply to climbing.
There is a pattern language to climbing areas. Hueco Tank's pattern language includes roof, crimps, and access. Red River Gorge's pattern includes steep, pump, and rain. A pattern language for a gym could be big feet, small reaches, and hand/heel matching.
Identifying a pattern language is a vital first step. If your current pattern language does not match your goal pattern language, a change is needed.
