Bonanza Cemetery

Bonanza, Wyoming today is a ghost town.  Nothing remains except the cemetery.  Early settlers (mid 1880’s) in this part of the Big Horn Basin discovered a natural oil seep which was used to lubricate their wagon wheels.  Hopes and rumors ran high that a “Bonanza” oil field had indeed been found but drilling rigs came and within a few years left the area.  The only remnants of the town are the cemetery and the postoffice which was moved to “Old Trail Town” near Cody, Wyoming.

Those buried here were mostly original settlers or their next generation.


The Bonanza Cemetery is located about 8 miles west of Hyattville at the junction of Hwy 31 and Road 31 ½.   Turn south on Road 31 1/2  and look for the fenced cemetery on the west side of the road.
