The Lugar Sill

Where the Glenmuir Water Water joins the Bellow Water the river passes through a Site of Special Scientific Interest (SSSI) called The Lugar Sill.^[4][5] The Lugar Sill is a geological feature which has been closely studied over many years. One of the many igneous rocks found in the sill is Lugarite,^[6] an extremely rare rock found only at this locality.^[7][8]
