The "mud volcanoes" from Sic village?

I heard from a colleague that there are some peculiar geomorphological shapes found on the edge of Sic village. I first thought that they could be mud volcanoes (for short MV) based on there shapes. I found no detectible emissions, nor sign of recent mud eruptions.

Starting to investigate the      "mysterious shapes".

The first measurement on the top of the biggest, presumable "MV".

A smaller one....

 A slightly bigger one...

  

Still trying to figure out what they are!  

During this campaing I had two helpers: my dad and my uncle!
