The object of this paper is to record and discuss the investigation of an unusually prolific Mesolithic chipping floor recently located on War Department land between Bordon Camp and the hamlet of Oakhanger, near Selborne, on the Hampshire Greensand. These lands are particularly sterile and undulating, and are dissected by a stream which emerges from Oakhanger Ponds to enter the Oakhanger Stream about a mile to the north (fig. 1). The section west of this stream is named the Warren, and that on the east is called the Slab. The site now being discussed is one of five located on the Warren and Slab, and is known as Site V. The group forms part of a series fringing the watercourse known sectionally as the Oakhanger Stream, Kingsley Stream, Oxney Stream, and the Slea, which eventually feeds the Frensham Wey. Thus the Oakhanger sites integrate with the important network investigated in West Surrey.

The Warren, together with the Slab, forms a roughly quadrangular area with its northern side coinciding, for about a mile, with the Bordon-Oakhanger road. Together they make up, approximately, a square mile of rough ground which is marshy along the course of the dividing stream. Geologically it is on Folkestone Sands which, in this area, are extensively covered by blown-sand deposits. Towards Oakhanger, half a mile to the north, these deposits are unusually thick and form dunes. In the Folkestones there is much carstone in thin layers which, here and there, tend to induce marshy conditions. The nearest chalk outcrop is some two miles to the westward in the Selborne district.
