Blue Mountain Forts. In 1763-64, from a line of six loghouse stations to the north, settlers were defended by the Paxton Rangers volunteers paid by Pennsylvania's Provincial government. Fort Hunter was on the Susquehanna just north of Blue Mountain, and the other five stations were just south of the mountain located at regular intervals over the 23 miles between the river and the Swatara Creek. A similar line of stations had existed, 1756-57.
