Green Gable's eastern face contains the slight hollow of Mitchell Cove, its stream joining Styhead Gill on the way to Borrowdale. At the northern corner is the ridge to Base Brown, the flat topped depression of Blackmoor Pots. The dale between the Base Brown and Brandreth ridges is Gillercomb, a classic hanging valley. Its stream, Sourmilk Gill, exits around the nose of Base Brown via a series of cascades to Seathwaite. This ensures that all of Green Gable's waters, bar those from the western face, reach the River Derwent. Brandreth connects via the narrow ridge of Gillercomb Head, site of a few small pools after wet weather. The Ennerdale side provides the gentlest slopes, at least at lower levels, with the long grassy spur of Tongue gradually rising up the fell. The topmost section however is guarded by Greengable Crags, stretching around from Stone Cove.
