West of the summit a broad ridge descends steeply to Worm Gill, a craggy bowl scooped out on the northern side above the tributary of Bleaberry Gill. Running due north between this corrie and Silver Cove is the ridge of Iron Crag, making the whole summit area resemble an inverted 'T' in plan. A narrow and steep sided col at 1,575 ft provides Iron Crag with considerably more prominence than its parent, a small tarn lying on the northern slope. The rock face giving Iron Crag its name overlooks Silver Cove, but is not particularly prominent. From this top the ridge swings west again, the rough northern flanks running above the shore of Ennerdale Water. The main features here are Mart Knott, Stair Knott and Boat How. The ridge now meets the headwaters of the River Calder and divides to embrace the valley, Crag Fell to the north and Lank Rigg to the south.
