GIANT HANDPRINT IN ANCIENT RUINS IN URAL MOUNTAINS

While watching the video linked below, I was stunned by what appears to be a gigantic hand print embedded in the wall of a megalithic structure.

YouTube user NewEarth (https://www.youtube.com/user/everhungriescatgang) 

has numerous videos translated from the russian language of expeditions into the Ural Mountains of Russia investigating recently discovered ruins and other unexplained sites.

the Image of the giant Handprint is at 14:29 in the video. 
 

Notice the possible six digits as the thumb is not visible. 

Earlier in the video it was proposed that the stone used in the construction of these walls were possibly some form of cement,

I have also heard others suggest this in ruins in Peru, and Sardinia. 

I truly hope these megaliths can be documented and explored thoroughly before they are destroyed.
