The site of a settlement and a coal mine in North Ayrshire, Snodgrass lies on the edge of Longford Misk, to the west of Bartonholm, on the right bank of the River Garnock. In the early 19th C. there was a coal mine where which was operated by Colonel Fullarton of Fullarton. The mine was abandoned in 1833 following inundation by the river but sold to Archibald Montgomerie, the 13th Earl of Eglinton (1812-61), in 1852, who re-routed the river, drained the area and exploited the coal as the Bartonholm Colliery.
The site of Snodgrass now lies next to the abandoned concrete dynamite stores, associated with the former Nobel Factory which lay across the Garnock on the Ardeer Peninsula. Its name is remembered as the 13th Hole on the nearby Irvine Bogside Golf Course.
