So now the degenerate druggies ( or at any rate the gangsters who supply them) are making it impossible for the world to learn about this ancient Mayan City.
The archeologists should be armed and have soldiers with them.
The British Victorians wouldn’t have put up with violent natives getting in their way like that.

I don’t think the British Victorians were very interested in letting the world learn about ancient cities. History shows they were more into desecrating sacred sites in a fit of arrogance.
