To the north-west of Bowfell the main ridge drops to the depression of Ore Gap, named after its reddish soil, rich in haematite. Below the col on the northern side is Angle Tarn. This round waterbody occupies a corrie beneath Hanging Knotts, small trout lurking in its 50 ft depths. Its outflow is a tributary of the Langstrath Beck, making for Stonethwaite. To the south of Ore Gap runs Yeastyrigg Gill, the main headwater of Lingcove Beck, flowing into the fastness of upper Eskdale. Beyond the Gap the ridge makes the stony three-tiered climb to the white-rocked summit of Esk Pike.
