Greenside Law
Greenside Law (643m) is a quiet whaleback in the Manor Hills west of St Mary's Loch, a tussocky dome above the headwaters of the Megget and Talla burns. The summit is unmarked — a patch of cropped grass among rougher tussock — and is most often reached as part of the long ridge sweep shared with Dollar Law and Black Law. Visitors come for the silence and the long views east over the upper Yarrow.

From the Megget Stone parking area at NT151206 a quad-bike track climbs the steep prow of Hunt Law before easing out onto the broad Cramalt Craig ridge. Greenside Law lies further east beyond a shallow saddle of peat hags, 12km return with 482m ascent. The ground is cropped sheep grass interlaced with hag systems that turn to porridge after rain. Return by the outward ridge.
Terrain
Short cropped grass dominates the ridge, but the watershed is broken by deep peat hags that braid the line of march. There are no waymarks and the summit itself is anonymous — a GPS or compass-and-pace approach is wise off the obvious ridge crest. The Megget Stone marks the start and is a useful catching feature on return.
In winter
In winter the Manor watershed feels much higher than 643m. Snow drifts settle deep in the peat hags and freeze hard into ankle-trapping pockets, while wind funnels through the gap above Talla Reservoir. SAIS Southern Uplands rarely issues bulletins this far east, but cornices can build along the steep northern edge dropping into the Megget cleuchs.
