Inland dune

In Central Europe, towards the end of the last glacial period (about 12,000 years ago), it was about 10 degrees colder than today.

Light, fine-grained soil particles, especially of silt and sand were plucked up by air currents, often transported for miles and then deposited at another location.

The shape of inland dunes varies depending on the prevailing wind direction and strength.

Nearly all recent phases of the development of inland dunes are affected by human intervention on the vegetation cover.

[1] The sands of the inland dunes of El Vizcaíno Desert, Baja California, Mexico, come from nearby alluvial sources.

[3] Near Copiapó in the southern reaches of the Atacama Desert the largest dunes of Chile exists.

[4] Inland dunes in the Gran Chaco of Bolivia and Paraguay are concentrated at the Andean foothills.

They were predominantly created under cold climatic, periglacial conditions at the end of the Weichselian and Würm ice ages, i.e. roughly more than 10,000 years ago.

[6] Inland dunes can also be found in Finnish Lapland north of the Arctic Circle and in Norway's Finnmark.
