I have posted a photo of this new downhill mountain bike track on Ryston Bank before. It’s quite a feat of engineering. I don’t begrudge the building of the track but I am concerned about the source of the sandstone rocks used to make the berms and ramps. Roseberry Common, beyond the fence and ruined dry stone wall, is National Trust land and it is the intention to rebuild the wall to provide shelter for birds, insects and small mammals. Something which will not be possible if the stones have disappeared.
