Beschreibungen/Notizen

• Stones lie within a well‐sorted coversand in central Poland. They 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. Copyright © 2004 John Wiley & Sons, Ltd.
