The large Kotyrdag mud volcano in the background. Kotyrdag, means “The bald man”.
Stiff mud extrusion by overpressured fluids on top of Kotyrdag mud volcano (picture slightly enhanced to show the extrusion clearer). This mud flow is about 3 km long and travels northwards to the adjacent plain.

Another overview of the mud extrusion in Kotyrdag, clearly showing the steepness of the northern slope of the mud volcano.
Side view of the mud extrusion on Kotyrdag. Note the brown sinters (baked clay), proving that there has also been burning gas near the summit vent of the extrusion.
Same as above. One has to imagine that the mud travels at a speed of some millimetres or centimetres per day (it was not able to measure the speed whilst there for only one hour, in 2002).
