Wyatt Earp's common-law wife, Celia Blaylock, died after drinking a lethal dose of laudanum and alcohol.
Born in 1850 and died in 1888, she is buried in the Old Pinal City Cemetery near Superior.

The grave was a little hard to find since the cemetery is not marked and the dirt roads are aplenty in this silver mining country.
You might want to stop for lunch at the delightful Cafe Piedra Roja on Main Street and get a map from the friendly owner. He can also direct you to places to look for Apache Tears.
