An archaeological evaluation was carried out to inform micro-siting of turbines at a proposed windfarm. Trial trenches were excavated at each turbine location, and also where the proposed access track for the windfarm passes close to Craikham Hill, a large mound of unknown date. Turbines 1-4, in the southern half of the site, occupy a gently undulating landscape formed by glacial till deposits. At Turbine 4, a group of features was revealed which appears to represent the remains of a settlement of late prehistoric and Roman date. Finds included Roman and prehistoric pottery and lithics, and features included at least one substantial ditch. No other features were identified at Turbines 1-3, or in the vicinity of Craikham Hill, although a flint core was found on the surface of the field close to Turbine 1. The trenches at Turbines 5-9 are located in an area of artificially drained wetland, Roos Carr: machine-excavated sondages at each turbine location found that homogeneous alluvial clay deposits continued to depths of over two metres throughout this area.
