The peak is 682 m (2238'), still a lot higher than this, the highest part of the route, at 310 m (1017'). Not bad, considering Lancaster is at sea level and at least 200 m (656') of the ascent was in the foregoing ~5 km (3 miles).
The incised course of the Gill Head stream is obvious, but this is a limestone area, and much of the drainage is subterranean. There are at least four named potholes in this field of view.
