This is a walk I did from Ingleton to Ingleborough (724 m), Chapel-le-Dale, and Whernside (736 m). These Yorkshire hills have a lot of memories for me: I first climbed them when I was just seven years old, and Ingleborough was the hill that made me fall in love with fellwalking (Whernside, not so much: I always remember it as a long slog).
These hills stand on the pediment of the Great Scar Limestone, a 180 m high band. The bulk of each hill is softer shale and sandstone, with thin bands of harder limestone resisting erosion and giving Ingleborough its stepped upper ramparts. Caps of millstone grit give the hills their flat summit plateaus. The upper rocks are largely impermeable, so water runs over the surface, collecting in bogs on the lower slopes. But when the streams reach the permeable and soluble limestone, they rapidly cut their way underground, leaving dry river valleys and a multitude of sinkholes, shakeholes, potholes and caves.
