The Grey Stanes of Garleffin were eight standing stones in the form of a half ellipse about 233 yards long, with two of the stones being only one yard apart. Local tradition said that a battle was fought here, and the stones marked the sites where chieftains fell. Only two of the stones remain in the 21st century, the others having been destroyed by farmers.
Within the same big field stretching from the standing stones north to the bridges, there are cropmarks of a four poster stone-circle, a round barrow, possible ring-ditches, and several pits
Findings of flints and other stone instruments show the presence of mesolithic and neolithic settlements south of the River Stinchar
Finnarts Hill has a circular earthwork, possibly a ritual enclosure from the Bronze Age. A farmer found a supulchral urn there which contained some human bones. In this area there was also a prehistoric burnt mound.
Human bones 'of enormous size' were discovered in a cairn on top of Carlock Hill, and other ancient cairns are to be found dotted around the hills.
Old and new place-names can be a fair indication of historical significance. Auchencrosh, for example, translates as 'the field of the cross', and Kilantringan as 'the church of St Ninian' – that area of Glenapp did have a chapel on the pilrimage route to the shrine of St Ninian in Whithorn. 20th century bungalows next to the Garleffin standing stones were named Druidslea and Glendruid.
Carrick separated from Galloway in the late 12th century. Three standing stones marked the southern boundary. The one at Little Laight at the end of a dyke is called the 'Taxing Stane', probably from its later use as a toll, and local tradition has it as the burial place of King Alpin or his father in the 8th century. Another stone has the name of 'Long Tom' or 'Long Tom Sloan' after a more recent shepherd, because it looked like him from a distance.
