|Felipe did it some time ago and today I try it similiar way - look at the picture - see ghost ready to be busted ;-) ? Also look at WS.|
This picture was taken in beautifull Slanic area. There was mountain made of salt and salt lake, 400km from nearest sea! Expect much more pictures from this region.
Unfortunatelly we were here only for about hour, so we hadn't got opportunity to visit old salt mines :-( But maybe some day...?
Solution phenomena occurring in rock salt by the action of groundwater. Although rock salt is considerably more soluble in water than is the calcite that forms karst topography, rock salt is impervious, and solution can take place only on the exterior surfaces. The brine formed by initial solution must be drained off by groundwater before more solution can occur.
