An archaeological watching brief was carried out by Mike Jarvis Archaeological Services in August to October 2008, during ground investigations in advance of a phase of construction forming part of the Ruston Way Enterprise Park, Lincoln. The investigations included five boreholes and the excavation for ten geotechnical trial pits. In conjunction with the geotechnical survey, two trenches, approximately 6m square and around 2.5m deep, were excavated for archaeological purposes. The investigations located natural sands, thought to form part of a sand island during the mesolithic and later prehistoric periods. {1}{2}
