Southern Upland Way

Megget Water is a river in the parish of Yarrow, Selkirkshire in the Scottish Borders area of Scotland. The Water rises at Broad Law (2,760 ft), passes through Megget Reservoir and empties into St Mary's Loch. Places in the vicinity include Cappercleuch, Craigierig, Cramalt Tower, the Glengaber Burn, Meggethead Farm. The Megget area, formerly a parish united with Lyne, Scottish Borders, is of geological and archaeological interest, through stone artifacts at Henderland in the lower Megget valley (now in Wilton Lodge Museum, Hawick), and discoveries of gold.

Cappercleuch is a settlement on the A708, at St. Mary's Loch in the Scottish Borders area of Scotland, in the historic county of Selkirkshire. Places nearby include Bowerhope Law, Craigierig, Deer Law, the Dryhope Tower, Ettrickbridge, the Ettrick Forest, the Megget Reservoir, the Megget Water, Mountbenger, the former Tibbie Shiels Inn, the Yarrow Water and the Glen Cafe overlooking the Loch of the Lowes.

St Mary's Loch is the largest natural loch in the Scottish Borders, and is situated on the south side of the A708 road between Selkirk and Moffat, about 72 kilometres (45 mi) south of Edinburgh.

Craigierig is a village on the Megget Reservoir, in the Scottish Borders area of Scotland, in the former Selkirkshire. Places nearby include the Glengaber Burn, Henderland, St Mary's Loch, the Tibbie Shiels Inn, and Yarrow Water.

Megget is a former chapelry or parish containing the valley of Megget Water, now forming the westernmost part of the parish of Yarrow, Selkirkshire in the Scottish Borders area of Scotland. The centre of the valley is 19 miles (31 kilometres) west of Selkirk. The district is bordered on the west by the parish of Tweedsmuir, on the north-west by Drumelzier and on the north by Manor (all in Peeblesshire). On the east side it is joined to the rest of the present parish of Yarrow, but formerly the parish boundary with Yarrow ran southwards from Black Law to Deer Law to Cappercleuch burn thence to St. Mary's Loch and continued down the west shore of the loch for almost one mile (1.5 kilometres) to Mare Cleuch by the Rodono Hotel. It is bounded on the south by Ettrick in Selkirkshire and on the south-west by Moffat in Dumfriesshire. Megget Stone lies on the western parish boundary, with Tweedsmuir.It is about seven miles (eleven kilometres) long north to south and about six miles (ten kilometres) wide with an area of 14,500 acres (5,900 hectares).The population of Megget in 1861 was 53 and in 1901 was 73. At the latest census (in 2011) the population of Megget was around 50.The parish of Megget derived its name from the river Megget, which took its name from the whey colour of its waters (Gaelic or old Welsh). Until 1891 it was part of Peeblesshire and thus part of Tweeddale, however "the water of Meggit is the only water in Tweeddale, that pays no tribute to Tweed; but runs from the south-east, some five miles [8 km], and ends its course in the bosom of St Mary Loch, and from thence, with Yarrow, watereth the wοόdy banks of the Forrest" (namely Ettrick Forest – the county of Selkirkshire).

Black Law is a hill in the Manor Hills range, part of the Southern Uplands of Scotland. One of the more remote Donalds, it does not easily combine into a round with other hills in the area and requires traversing rough terrain to reach the top. Common ascents are as part of an extended Dun Rig Horseshoe to the north-east, from the south at the Megget Reservoir or, most easily, from the Manor Valley itself.

Dob's Linn is a small steep valley in Dumfries and Galloway, just north of the A708 road between Moffat and Selkirk, in Scotland. It is part of the Grey Mare's Tail Nature Reserve which is owned by the National Trust for Scotland. According to tradition, Dob's Linn is named for a covenanter, Halbert Dobson, who took refuge there from Government troops during The Killing Time in the late 17th century.Dob's Linn is important in geology as the location of the Global Boundary Stratotype Section and Point (GSSP) which marks the boundary between the Ordovician and Silurian periods, and marks the base of the Llandovery epoch, on the geologic time scale. Dob's Linn was ratified as the GSSP by the International Union of Geological Sciences in 1984.The boundary is defined as the first appearance of graptolites Parakidograptus acuminatus and Akidograptus ascensu 1.6 m above the base of the Birkhill Shale Formation. The shale section also contains chitinozoa and conodonts, but neither are well preserved. Dob's Linn has been criticized for the difficulty in relating its graptolite biostratigraphic sequence with shallow water sequences elsewhere, although the stratotype also appears to correspond with a carbon-13 isotope excursion in the latest Ordovician which can be identified worldwide.The area was first studied by Charles Lapworth in the late 19th century. His work established fossil graptolites as a method of understanding stratigraphic sequences. A more recent description of the area, enumerating the zones established by Lapworth, is given in the British Regional Geology Monograph. Before Lapworth's work, it was thought that the Silurian rocks of the Southern Uplands formed a single sequence, that would have to be about 6000m in thickness. By his identification of particular graptolite species in different zones of the Dob's Linn exposure, Lapworth was able to demonstrate that the Uplands consist of a much thinner layer, consistent with Silurian deposits elsewhere, that had been repeatedly folded and faulted, with multiple repetitions of the same strata, often upside down. The understanding that sequences of sedimentary rocks could be inverted played an important part in the later resolution of the Highlands Controversy in which Lapworth was also involved.

Megget Reservoir is an impounding reservoir in the Megget valley in Ettrick Forest, in the Scottish Borders. The 259 hectares (640 acres) reservoir is held back by the largest earth dam in Scotland. The reservoir collects water from the Tweedsmuir Hills, which is then conveyed 28 miles (45 km) via underground pipelines and tunnels to Edinburgh. The pipelines are routed through the Manor Valley and the Meldon Hills, to Gladhouse Reservoir and Glencorse Reservoir in the Pentland Hills. These two reservoirs store the water until such times as it is required. Excess water which overflows from the reservoir is returned to the Megget Water, and hence into St. Mary's Loch.

Andrewhinney Hill is a hill in the Ettrick Hills range, part of the Southern Uplands of Scotland. It is the highest summit of a ridge that runs parallel to the A708 road on its southern side, with the Grey Mare's Tail in the Moffat Hills directly opposite. The northwestern slopes are designated as part of the 'Moffat Hills' SSSI and SAC.

The Southern Uplands (Scottish Gaelic: Na Monaidhean a Deas) are the southernmost and least populous of mainland Scotland's three major geographic areas (the others being the Central Lowlands and the Highlands). The term is used both to describe the geographical region and to collectively denote the various ranges of hills and mountains within this region. An overwhelmingly rural and agricultural region, the Southern Uplands are partly forested and contain many areas of open moorland - the hill names in the area are congruent with these characteristics.

Grey Mare's Tail is a 60-metre (200 ft) hanging valley waterfall near to Moffat in southern Scotland. The fall is produced by the Tail Burn flowing from Loch Skeen cascading into the Moffat Water in the lower valley below. The surrounding area forms the Grey Mare's Tail Nature Reserve, owned by the National Trust for Scotland. The footpath from the valley floor up to Loch Skeen is one of the more popular walks in the area. Parking is also provided. Grey Mare's Tail Nature Reserve is situated along the Moffat Water Valley in the heart of the Southern Uplands. This National Trust for Scotland property extends over 922 hectares and is characterised by a dramatic waterfall (the 5th highest in the UK), an upland loch Loch Skeen and White Coomb which rises to 821m and is one of the highest hills in Southern Scotland. The post-glacial landscape is an open mosaic of heather and rough grazing that includes 8 habitats of European importance and many plant species of international, national and regional significance. The reserve is botanically diverse, containing the richest assemblage of rare upland plants in Southern Scotland. Recognised as a Special Area of Conservation, Grey Mare's Tail Nature Reserve is popular with hill walkers, botanists and wildlife enthusiasts. There is also historical evidence of Iron Age settlers and the Covenanters who sought sanctuary here in the 17th century. Notable animal species: peregrine falcon, ring ouzel, raven, vendace and wild goats. Rare plants: many, including oblong woodsia, montane willows, and alpine saw-wort.

Dun Rig is a hill in the Manor Hills range, part of the Southern Uplands of Scotland. It is the highest hill in the northernmost cluster of the Manor Hills, south of the town of Peebles in the Scottish Borders. A sprawling summit, it is usually climbed as part of the Dun Rig Horseshoe from the Peebles side and provides great views into the Moorfoot Hills, Pentlands, rest of the Manor Hills and the central Borders. It is the historic county top of the former county of Selkirkshire.
