Q: 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. Some walkers therefore doubt Bache Hill's 2000-foot status. However the latest OS Explorer Maps shows a large 610-metre contour round the summit.
