FRANKFORT — The Kentucky Historical Society will dedicate a historical marker to a pioneer outpost and spring at Mount Sterling later this month.

The June 29 ceremony will be at the site where settlers built Fort Baker in 1790. It was one of 36 pioneer outposts crucial to the settlement of Clark, Montgomery and Bath counties. The Historical Society says the station, established by John Baker, covered 20 acres and included a natural spring.

The fort was evacuated after a June 29, 1790, attack by Native Americans.

Although the outpost was abandoned, several men returned at season’s end to harvest the corn crop they had planted.

The spring and well was visited by President Andrew Jackson in 1832.
