The Buttermere- Ennerdale watershed descending from Brandreth is initially indistinct, running north west across a broad plateau. After half a mile it reaches the rocky protuberance of Great Round How (1,817 ft) and then its character changes completely. The watershed narrows to fine ridge, steep enough on the Ennerdale side and rimmed by crags throughout above the head of Buttermere. The beauty of the scene is completed by a succession of rocky tops and nestling tarns, until the high point is reached at the western end. A sharp descent over rock now follows, leading to Scarth Gap (1,460 ft), a walkers' pass between the two valleys. Beyond the ridge rises again to High Crag, a steep climb on scree.
