On the east, the first impression is all of rock. The long strath of Grisedale runs north-eastward to Ullswater, cutting off a series of hanging valleys which fall from the Helvellyn range. To the north-east of Dollywaggon Pike, below the summit of High Crag, is Ruthwaite Cove, a corrie surrounded on three sides by crag. Ruthwaite Cove is now the site of Ruthwaite Lodge, a climbing hut. It was formerly the setting for more industrious activity, with the remains of several levels and some shallow open mineworking being visible near the Lodge. These excavations were made for lead-bearing galena, and are believed to have been worked in the sixteenth century. Further leases were taken out in 1784 and 1862, the last-known operation being in 1880. To the east of Dollywaggon Pike is a second corrie, Cock Cove, with Falcon Crag and the deeply gullied Tarn Crag providing the impressive headwall.
