I didn't push on to the end as it was a bit of a rock scramble. At this stage there also was a little more cloud moving in. Worth viewing large. I once asked a geologist friend about the type of rock similar to this - his response was that it is fubarite. I'll let you look that up. :-))

(I originally had the geological term slightly incorrect, now fixed on the advice of sigwv who is a geologist.).
