The Glencartholm Volcanic Beds[2] contain a Palaeozoic (specifically Carboniferous[1]) fossil fish site of international importance. Discovered in 1879, most of the fossils were removed during the 1930s, but in the 1990s a further site 50 m (160 ft) east, named Mumbie, was excavated. This led to the identification of further fish beds, where over 200 specimens of ray-finned fish were collected, including one possible new species[3]
There is also a farmhouse known as Glencartholm, or Glencartholm Farmhouse, which is a listed building[4] in the parish of Canonbie, not far from the border with England,[5] and near Glencartholm Wood. The farm has an inscription celebrating the defeat of Napoleon at the Battle of Waterloo.[6]
