Blanche's Bump
From Festipedia, hosted by the FR Heritage Group
In the 60's Blanche had a prang in the woods, this location now carrying the name "Blanche's Bump".
The location is between Trwyn-y-Garnedd (above Cei Mawr) and Gysgfa crossing, more precisely coming immediately after Trwyn-y-Garnedd top curve and the informally named "Tro Bocs Cachu", and before Gysgfa curve and crossing.
