Summary

Description
Deutsch: Das seenreiche Gebiet des Mackenziedelta liegt in einer Zone mit mächtigem, kontinuierlichen Permafrost. Unter den tieferen Seen existieren jedoch ungefrorene Bereiche (Taliks) die allseitig von Permafrost umgeben sind. Im Vordergrund hat sich durch Erosion ein wenig tiefer See entleert (Erosion an der nahe gelegenen Küste). Durch die jährlichen Gefrierzyklen entwickeln sich entlang den polygonal angeordneten Kontraktionsspalten auf dem ehemaligen Seeboden große Eiskeilpolygone. Aufnahme: Lorenz King, JLU Giessen.de, 7. August 1987
English: The Mackenzie delta is an area with thick continuous permafrost. However, unfrozen areas (taliks) may exist below the lakes shown. In the foreground, a small lake has been drained due to erosion (close to the coast). Ice-wedge polygons along contraction cracks slowly developed due to yearly freezing and melting cycles. This lake shows large low-centered polygons, more polygons can be recognized also between other lakes. Photo: Lorenz King, JLU_Giessen.de, August 7,1987
