“Historic Orchard Knob - Established 1835” ?

There are new signs stuck in the ground around the Orchard Knob area east of downtown Chattanooga that claim ‘Historic Orchard Knob - Established 1835’. Given that this area south of the river was Cherokee Nation up through 1838, and that the geographic feature was called ‘Indian Hill’, and that there is no publicly available information on the web about ‘Historic Orchard Knob’, - does anybody know where the idea of ‘Historic Orchard Knob’ being established in 1835 comes from?
