Agen Allwedd - high level passages

[Joe Duxbury]

Along Main Passage in Agen Allwedd are holes high up in the walls. One of these has a line of spits leading up to it. Who put them in, and where did it lead to? Also, high up in the LH wall of the slope leading up to Erse Passage, there is a single piton. Again, who put that in, and did the passage up there lead anywhere? Both spits and piton are quite old.
