The main watershed runs broadly westwards from Great Gable, dividing the headwaters of Ennerdale and Wasdale. The main fells in this section are Kirk Fell, Pillar, Scoat Fell, Haycock and Caw Fell. The surrounding valleys gradually diverge until at Caw Fell they are 6 miles apart and other rivers spring up to drain the intervening country. The Bleng rises to the south of Caw Fell, while Worm Gill drains the western slopes. The fell is therefore the end of the westerly run of the ridge, and the watershed curves north around the head of Worm Gill, crossing the subsidiary top of Iron Crag on the transit to Crag Fell and Lank Rigg.
