only for improving our understanding of their long-term, decadal– centennial scale, palaeoclimatic history (e.g., Overpeck et al., 1997) but also for developing more accurate climate models that include Arctic amplification. In particular, existing attempts to understand the environmental and climatic history of west Beringia have been ice-cover with open-water conditions today typically lasting from July to October (Nolan et al., 2003). The catchment, 293 km2, is small relative to the lake surface areawith vegetation characterised by discontinuous lichen and herbaceous taxa and permafrost extending down to depths of 100–300 m (Glushkova,1993; Lozhkin et al., 2007). Importantly, there is strong evidence that neither Lake El’gygytgyn nor the catchment have been glaciated since the lake’s formation, with the nearest evidence of glacial activity located ca 40 km to the west of the catchment (Glushkova, 2001; Glushkova * Corresponding author.
