Rocks along I-75 northbound heading to Chattanooga

There are some rocks on a ridge on the east side of 75 northbound between mile marker 336 and 341. They are visible from the highway and a quick google satellite search shows that there are more than what is readily seen.

Does anybody know anything about these rocks? Have they been climbed? Access?

They are ok, but difficult to get to. On private land. I checked them out a long time ago. Gated after they built a tower and some communications equipment, but that's been 15 years or more.
