The Rhiangoll River's Journey
The Rhiangoll River begins its journey high up on the western side of Waun Fach. This mountain is the tallest point in the Black Mountains. From there, the river flows quickly downhill towards the west.
Where the River Flows
As the Rhiangoll flows, it passes through a valley that runs from north to south. The A479 road also follows this valley. The river goes past the town of Talgarth and the small village of Tretower. It also flows right through the village of Cwmdu.
Streams Joining the Rhiangoll
Many smaller streams join the Rhiangoll River along its path. These are called tributaries. Some of these streams, like the Ffinnant and Nant yr Ychen, flow into the Rhiangoll from its left side. Other streams, such as those from Mynydd Troed and Mynydd Llangorse, join the river from its right side. Nant Ewyn also joins the Rhiangoll near the village of Bwlch.
How the Valley Was Formed
The valley where the Rhiangoll River flows was shaped a very long time ago by huge sheets of ice. These were from the Ice Ages. As the ice moved, it carved out the valley, making it wider and deeper.
Ice Age Influence
During the Ice Ages, the ice from the Rhiangoll valley joined with a much larger glacier. This big glacier flowed down the main Usk Valley, past Bwlch. This joining of ice helped to create the wide, lower part of the Rhiangoll valley that we see today.
Where the Rhiangoll Ends
After its journey through the valley, the Rhiangoll River eventually flows into the River Usk. This meeting point is near a place called Glanusk Bridge, which is about one mile south of Tretower.
