The Indian Mound cemetery in Ithaca, Nebraska was a revelation. It is a spotless, immaculately kept graveyard that puts most others to shame. The older gravestones are still almost perfect.
The University of Nebraska has a lot of the history of the small towns in the state online...here is the link for Ithaca.
The gazebo has a some cemetery history, notes on the symbolism of gravestone markings, and a list of the veterans buried in the cemetery.
