Lammermuir Hills

The Lammermuirs are a range of hills in southern Scotland, forming a natural boundary between East Lothian and the Borders.

[1] The Lammermuir Hills are formed from a succession of Silurian and Ordovician age marine sediments known as greywackes together with siltstones, shales and mudstones.

Unconformably overlying these highly faulted and folded strata are outcrops of the early Devonian age Great Conglomerate Formation which forms a part of the Reston Group of Old Red Sandstone rocks.

Glacial meltwater channels are common along the northern and eastern margins of the hills, with a notable group beneath Newlands Hill and Dod Law to the southeast of Gifford and north of Deuchrie Edge and Lothian Edge, largely directed towards the northeast in these areas.

[3] Spanning the counties of Selkirk, East Lothian, and Berwick, the Lammermuirs extend from the Gala Water to St Abb's Head, and offer a traditional site for sheep grazing.
