The eastern side of the fell forms the head of Swindale proper, the upper valley being known as Mosedale. Swindale is a classic U-shaped valley, its profile almost a square section, with a flat base and sheer walls. Selside Pike's eastern slopes fall gently to about the 2,000 ft contour and then plunge over a wall of crag to the valley floor. Geordie Greathead Crag is the dominant feature and below this is the dry tarnbed of Dodd Bottom. Hobgrumble Gill falls down this face in a deep gully, separating Selside Pike from the north east ridge of High Howes. Above the crags the gill runs in a small hanging valley.
