DUNES ON THE VISTULA SPIT
The shaping of the Vistula Spit is a result of a combination of sea water, land water and wind. The dunes on the Vistula Spit are fixed forms, mostly covered with forest or dune vegetation. Right along the spit, there are two belts of dunes which are parallel to each other. Most of them are around fifteen to twenty metres high with highly varied widths. The exception, of course, is the “Camel’s Hump”.
The dunes boast irregular shapes and sides with steep slopes, thus creating an extremely dynamic landscape on the Vistula Spit. The oldest, lowest brown dunes are located in the southern part of the spit and are adjacent to the Vistula Lagoon. The highest, younger yellow dunes, which are over 20 metres high, separate the partially covered brown dunes from the youngest white ones (situated right by the shore of the Gdańsk Bay).
In the vicinity of Krynica Morska, the yellow dunes reach the shore, where they are undercut in an abrasive way. Steep cliffs up to 10-15 metres in height, with a slope of over 30 degrees, are visible.
