Relict periglacial wedge structures are widespread in mid-latitude and polar regions. The wedges have a high preservation potential and are often infilled with quartz-rich aeolian sand, making them potentially suitable for luminescence dating. This paper presents initial work from an anti-syngenetic sand wedge in the Tuktoyaktuk Coastlands, Arctic Canada. When samples were measured at the single grain level they showed poor palaeodose (De) reproducibility and consequent high age uncertainties. The aim of the study was to determine whether this intra-sample De scatter reflected methodological issues arising from OSL measurement or processes of wedge development.
