In the 1980s the North Wales Arts Association and Manpower Services Commission developed a scheme for six youths to be employed renovating a council dump near Rhosgadfan in the Arfon slate country. Jonah noted in his journal that the setting was “seething with character. It has that primordial Celtic thing of being within sight of the sea and yet being secret and hidden away, up on a height that outsiders would be wary of approaching.” A great cilfach (enclosed site) was built, and Jonah fixed to it a plaque commemorating the writer Kate Roberts (1891–1985), a native of the local community. Years later the council had to remove the stone after it was vandalised. It is now in storage with a view to re-siting it somewhere more secure.
