This place is begging for a photogrammetric/lidar survey! Very impressive. Interesting comparison to the seismic scale features of salt deformation in Chris' paper (esp. Fig. 9). Well if anyone has a pile of rubles burning a hole in their pocket you know who to call...

In these pictures, Rock Salt is stronger than Carnallite, but is other places Rock Salt is clearly softer than Anhydrite. The shape of the folds can be used to quantify the contrasts in rheology, and such structures at the km- scale can now be studied in 3D seismic cubes. For those of you interested in this topic, there is a session at the upcoming EGU conference which discusses these rheological contrasts and their effects on the internal structure of deformed salt, and on the initiation of suprasalt sedimentation. http://meetingorganizer.copernicus.org/EGU2014/session/14740 regards, Janos Prof. Dr. Janos L.

This place is way more easily accessible than Yekaterinburg salt mines as there is underground museum there etc., and there are many international and domestic flights to Krakow (Wieliczka is located on outskirts of Krakow).
