White edge is a rocky edge that runs north to south across Big Moor. It doesn't have the sheer cliffs of some of the other edges, but it feels more remote and offers great views. The highest point is the trig point at the northern end where it reaches about 1,220 ft (372 m) The trig point stands a bit lower at 1,198 ft (365 m).
The trail along the whole edge is great to run and works very well as a loop with the trail along Froggatt and Curbar edge.
