I have always loved the (in terms of climbing and geology) so no trip to North Wales would have been complete without a substantial amount of time spent here. This is not intended as a in depth review of either the geology or the climbing, more like a few photos, words and thoughts. A really great article on the climbing can be found on UKC.
So what is slate? Slate is a metamorphic rock (meaning that it was previously another rock which was heated up and pressurised without melting causing physical and chemical changes). The rock which made up the slate previously was probably a fine grained sedimentary rock (such as a shale).
Good things about climbing on Welsh slate:
- Quick drying: this is wales we are talking about so it will rain and with some routes climbable only 15mins after a shower it can save a damp days climbing!
- Unique routes
Good things about the geology of the Welsh slate:
- Fantastic exposure of a large area
- Lots of interesting features worth seeking out including; the slate itself, igneous intrusions, relic bedding in the protolith and hydrothermal veins
Overall if you have never visited the abandoned quarries near Llanberis it is well worth the effort to explore the unique landscape found here.
