The features termed hill dunes by Goodier and Ball (1975) consist of areas in which eroded sand-sheets capped by vegetation stand as remnants above deflation surfaces. The name is therefore somewhat misleading, as the ‘dunes’ are not constructional features. The sands have a distinct stratification: a surface horizon of about 0.1 m of grey sand overlies a yellowish-brown sand to a depth of 0.7 m, with a buried surface horizon between 0.7 m and 0.84 m, a second bed of brown sand to 0.94 m and then a further buried surface horizon at 0.9-0.95 m, with underlying sand to 1.2 m. Below the sands is a diamicton consisting of weathered sandstone clasts with an iron-stained exterior in a sandy clay matrix. This material also armours the deflation surfaces. The stratification of the sand deposits is indicative of alternating periods of stability and sand movement, but no studies have been carried out on the age of the deposits. Similar sand-sheets and interbedded soil horizons have been described on Ronas Hill, Shetland (Ball and Goodier, 1974), and on An Teallach (Ballantyne and Whittington, 1987). At the latter locality it was demonstrated that sand deposition began in the early Holocene but was much reduced by the establishment of vegetation cover during the Holocene. However, recent disruption of the vegetation due either to climatic deterioration or to overgrazing has resulted in a renewed phase of sand erosion and re-deposition. A similar history may apply to the Ward Hill sands.
