A carefully constructed stone cairn, forming a roughly conical shape, sited at the highest point on Gwadana mountain. This marker was originally constructed as a survey pile during an early trigonometrical survey of the Transkei to permanently mark this position. The pile has since been modified into a formal trigonometrical survey beacon, numbered GW-NA. The pile was capped with a large hammer dressed roughly circular stone with the identification code GW-NA scratched into the top face of the stone. A circular pipe sleeve was let into the centre of the stone capping to accommodate a vertical steel shaft with four square sheet metal vanes attached to the upper end. The sleeve would have permitted the shaft to rotate but the shaft has been removed and all that remains are the faint circular witness marks in rust, staining the top face of the stone.
