Context: Bache Hill is a subsidiary summit of Rhos Fawr or Great Rhos in the Radnor Forest in Wales. It is located to the east of Black Mixen. The summit is marked by a trig point built on an ancient burial mound. Some controversy arises from the burial mound; in that 610 metres might be the top of the man-made mound.
