Abstract

This short note draws attention to the incorporation of stones from an underlying pebble layer into a layer of well-sorted and non-frost susceptible sand. The stones are thought to have migrated to their present positions by upfreezing that occurred as permafrost aggraded beneath an accumulating dune-sand surface. Some of the stones have risen as much as 1 m into the coversand. Chimney-like sedimentary structures are thought to indicate the path of upward migration. The dynamics of upfreezing in non-frost susceptible sediment are difficult to understand without recourse to site-specific factors
