  • $\begingroup$ you need to give more details,like what type of rock is it.i guess you are asking if this rock have been shaped like this by people,the first thing you need to ask is this made of a material that can be used to make a tool.if not it have to be a natural rock that just happen to be shaped like this. $\endgroup$ – trond hansen Mar 18 at 8:10
  • $\begingroup$ What strange blue tint - did you photograph this during dawn? Please take new pictures (read the guide), because how can anyone give decent advice with these false colors? $\endgroup$ – Jan Doggen Mar 18 at 8:52
