Keystone, North Dakota

Keystone is a former unincorporated community (ghost town) in Keystone Township, Dickey County, North Dakota, United States.

History
Keystone was originally built up by settlers from Pennsylvania, and the name taken from that state's nickname, the Keystone State. The beginning of Keystone was about a mile north of where the town was finally established. There was a $3000 church built in Keystone which was used there as long as the town lasted and then it was moved to Monango.
