To the south-east of the fell is the valley of Deepdale, separating St Sunday Crag from Hart Crag and Hartsop above How. This face too is steep and rough, although without sustained outcropping of rock. Between Gavel Pike and Birks is Cold Cove, a hanging valley cut off by Deepdale. All of the becks from St Sunday Crag reach the head of Ullswater at Patterdale.
