Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. Black Mountain
(Welsh: Mynydd Ddu) is a mountain in the Black Mountains (not to be
confused with the Black Mountain range of hills,or the Black Hill just 2
km east). It is the only Marilyn to fall exactly on the Welsh-English
border, straddling Powys and Herefordshire. Its parent peak, Waun Fach
lies to the west. The Black Mountain is the highest point on Hatterall
Ridge. Offa's Dyke Path passes along the ridge, more or less from south
to north (or vice versa), while a steeper path leads to the summit from
near the former youth hostel in the Vale of Ewyas to the west. The
summit is unmarked and, because of the very shallow gradients along the
summit ridge, virtually impossible to determine in situ.
