Image of Pen Cor-Maen, Pumlumon (Standing Stone / Menhir) by GLADMAN

Pen Pumlumon Fawr from Banc Llechwedd-mawr’s cairns to the approx north-west. From here one can view the first cascades of the nascent Afon Rheidol from it’s rising within Llyn Llygad-Rheidol.... Pumlumon’s hidden watery eye. LLyn Pen Cor-Maen can (I reckon) just be seen centre right of image, the northernmost of a series of small lakes set upon the lower rocky spine seen here (Fainc Ddu). The stone, if it still exists, is a little to the left (north).
