INTRODUCTION The Bhaltos peninsula in Uig Parish, Lewis, has been a focus of archaeological activity for many years. The peninsula lies on the exposed west coast of Lewis, less than 20 km from such sites as Dun Carloway and the Callanish stones (illus 1). The present survey began in 1989 as part of a wider programm f surveo e excavatiod an y n Edinburgcarriey b t ou d h University's Callanish Archaeological Research Project which has also included the excavation of later prehistoric sites at Dun Bharabhat and Loch na Berie (Harding & Armit 1990).

The machair environment, which forms the focus of the present study, dictates to a large extent the nature of the survey and the presentation of the results.
