Since I live within a few minutes' drive of it, I guess the first thing I ought to do is post a link for the Kennesaw Mountain National Battlefield Park:
For those who aren't familiar with the battle, here's a nice summary:
And for your viewing pleasure, here are a couple of shots of the mountain:
*Well, recently, anyway; this is actually a postcard view, date uncertain, but it shows the
mountain's distinctive twin "humps" (the summits of Big and Little Kennesaw Mountains).
Kennesaw Mountain is roughly 1,800 feet above sea level; however, about half of that height is part of the Appalachian Mountain plateau on which the mountain is located. By way of comparison, Cedar Mountain, VA (where another battle was fought in 1862) is 813 feet above sea level*, roughly the same height from foot to summit, although it sits in the Virginia piedmont rather than on the Appalachian plateau, leaving it 1,000 feet short of Kennesaw's total elevation (plateau + mountain).
Next up: a history of the park.
