If you're curious the linked article has pretty much all the infomation available.

It was written by Alex Wellerstein,

  a historian of science and nuclear weapons and a professor at the Stevens Institute of Technology. 

who has likely looked over almost all the unclassified US bomb test material, read a substantial amount of it, and at various time has had access to classified portions.

The article has three addendum, updates as more information came to light about the name of dancer, the photographer, the article series that was published, etc.

It's bound to more informative than anything I could tell you given I'm in AU not the US and know somewhat more about Emu Field and the Montebello's than I do about Yucca Flat.
