The high point of the fell lies on a line of tors which break through the peat and fellgrass toward the east of the plateau. Travelling south from the Eskdale rim the tops are Kepple Crag, Great Whinscale, Crook Crag (1,538 ft), Green Crag and White How. The crest then turns west toward the Fell Road, passing over Great Worm Crag (1,400 ft), considered by some to be a separate fell. To the west of the summit ridge is Low Birker Pool, a tarn which feeds Birker Force. This shallow waterbody is contained by a low moraine and overlooked by Tarn Crag.
