The Eastern Fells consist of a long north-to-south ridge, the Helvellyn range, running from Clough Head to Seat Sandal with the Helvellyn at its highest point. The western slopes of these summits tend to be grassy, with rocky corries and crags on the eastern side. The Fairfield group lies to the south of the range, and forms a similar pattern with towering rock faces and hidden valleys spilling into the Patterdale valley. It culminates in the height of Red Screes overlooking the Kirkstone Pass.
