There was more of the bicycle path along the Tuscarawas River between the county line and Bolivar. It was OK as far as it went.
If the museum had been open, I would have asked whether there were any historial markers at the end of the Greenville Treaty Line. But it had closed at 4pm.
The museum had been built before archaeological work was conducted to identify the exact location of the fort. It turned out the museum was "uncomfortably close" to the site, which had been presumed further away. The path in the grass to the right of the marker identifies part of the outline of the fort.
