Haycock's southern flanks are bisected by the ridge to Seatallan and Middle Fell. This begins steeply over Gowder Crag and then broadens over High Pikehow before finally reaching the depression at Pots of Ashness (1,640 ft / 500 m.). To the west is the head of the River Bleng, Haycock's daughter stream. This flows south-west for some miles, remote from habitation. Finally it joins the River Irt and enters the sea at Ravenglass. On the opposite side of the south ridge is the valley of Nether Beck, making straight for Wast Water.
