South Down Summit
The summit of South Down is a grassy knoll with little of note to excite the geologists. However, just off the tops there is exposed metamorphic rock that would warrant their attention.
To the south-west of the summit, at grid refrerence SX 5550 9111 and at an altitude of 370 metres, there lies a rather scruffy pile near field boundary walls. The public footpath runs to the north-west of this emergent outcrop. Its western section consists of sparse rocks whilst the more prominent outcrop to the east is more dramatic. Here, the down falls away to Meldon Reservoir and the view of Longstone and Homerton Hill is quite special.
At grid ref SX 5565 9137, north of the summit, there is a section of low exposed bedrock and fragmented boulders located either side of a ruined wall. From afar you see the grouping of this exposed metamorphic rock to best effect, an obvious scar on the western edge.
