Is there one place on earth where we can see the complete geologic column? how and why?

No, nowhere in the Earth a complete geologic column can be seen.  

Explanation:

Geological column has no existence in reality, it is hypothetical and it is based on European crops that are rock based as stated by the creationists. It is used to make rock classification all over the globe.  

However, there is debate from anti-creationists in response to the existence of this column and they claimed that it has a logical structure. But, no such column can be found in the whole world. The one reason behind its non-existence is thought to be the erosion.
