A Caveman Once Lived Here!

Yes, it`s true!  Flintstone himself once lived very close to GZ.  I`m not sure why he moved on, or where he moved to, but this was once his home. (or at least home for one of his caches).  Me thinkst that the caveman liked to consume bronto-burgers and cactus juice, at the near-by establishment, which, coincidentally is named after one of the caveman`s greatest inventions!

You`re looking for a small lock n lock within a sort of typical, caveman dwelling.  Good luck!
