Hope County Jail is a Far Cry 5 location that comes back as a memory in the Joseph: Collapse DLC for Far Cry 6. In Far Cry 5 it was the resistance stronghold in the Henbane River region.
In Far Cry 5 the jail sits in Henbane River, Hope County, Montana. Virgil Minkler and the Cougars used it as the main resistance base in Faith Seed's region.
The Joseph: Collapse DLC takes place inside Joseph Seed's mind. Hope County Jail is one of the Far Cry 5 places it brings back.
Faith manipulates Marshal Burke into killing Virgil and opening the gates to the cult. The Deputy later clears the cult out, and the jail goes back to sheltering the wounded.
