The highest ground in the North Western Fells is an east-west ridge in this central sector, beginning with Grasmoor above Crummock Water and then gradually descending eastwards over Crag Hill, Sail, Scar Crags and Causey Pike. Grasmoor has the greatest elevation, but Crag Hill stands at the hub of the range. In plan it appears as a cross with ridges running to the four points of the compass.
