This is what I'll call a recreation of the Tombstone cemetery. The original grave markers and most of the locations are lost to history.
This is the location of the graveyard, and the residents are all well documented as are the epitaphs.
Unfortunately it all looks like it was just created yesterday. Most of the markers are metal welded to pipe stuck in the ground - not very convincing.
Still, it was an interesting visit and admission is whatever you choose to donate.
