Northumbrian burr

A 19th century dialect map indicating the range of the Northumbrian burr within Northumberland and Durham.

The Northumbrian burr is the distinctive uvular pronunciation of R in the traditional dialects of Northumberland, Tyneside ('Geordie'), and northern County Durham, now remaining only among speakers of rural Northumberland, excluding Tyne and Wear. It is one of the few rhotic dialects left in England.[1]
