Landslide on Graig Road between Godre'r Graig and Ystalyfera

In 1965 part of Mynydd Allt-y-grug slipped down over this section of road sweeping away all the houses either side of it. The road has only ever been reopened as a much narrower path for light foot traffic. In the photo you can see how much the landslide has reduced the width of the road. However this is not the whole story: a few hundred yards further back the road is a third wider again with a pavement on both sides. The landslide is thought to have been triggered when a water main supply was accidentally ruptured, allowing water between layers of otherwise impermeable rock. Even now at the southwest end of the landslip there are extra drainage pipes running down the mountain to help prevent further occurrences.
