There are three common attributes for the name Kennesaw. George White, one of the earliest writers about the state said it was the Cherokee name of the man settlers knew as "Cabin." Others believe the name to be a variation of the Cherokee word Conasauga meaning "grass." The National Park Service attributes the name Kennesaw to the Cherokee Indian word for cemetery or burial ground, "Gah-nee-sah." Author Richard Thorton, in the book Ancient Roots, attributes the name to a Muskogee word meaning "Raccoon People."
The mountain is locally known as "Big Kennesaw" to distinguish it from its closest neighbor, Little Kennesaw Mountain. Until the 20th century it was also commonly spelled with one 'n', Kenesaw Mountain.
The mountain is entirely located in Cobb County, Georgia and its peak is 1,808 feet above sea level and roughly 800 feet above the surrounding countryside. Most geologists consider the mountain to be in the foothill region of the Appalachian Mountains and part of the Georgia Piedmont. It is one in a series of isolated peaks in the Piedmont that include Stone Mountain, Arabia Mountain, and Graves Mountain.
From Kennesaw Mountain running south the ridge is formed by Little Kennesaw Mountain, Pigeon Hill, which was called Kennesaw Hill in 1864, and Cheatham Hill. The string of mountains is considered to be within the Brevard Fault zone and is mostly medium to fine-grain gniess with varying amounts of biotite, muscovite, plagioclase, quartz, and microcline. Rock outcrops rarely exceed 600 feet in length, and there is granite on the east side of the mountain with a large amount of quartz.
A 2006 study of Flora showed the most common plants to be:
73 species of Asteraceae (includes asters, daisies and sunflowers)
69 species of Poaceae (true grasses)
39 species of Fabaceae (legumes)
21 species of Rosaceae (roses)
19 species of Cyperaceae (sedge)
14 species of Lamiaceae (mint)
Kennesaw Mountain Battlefield is a 2,923 acre National Battlefield preserving the largest battle of The Civil War fought in Georgia. The battle was fought during The Atlanta Campaign on June 27, 1864 although fighting occurred in the area from June 19, 1864 until July 2, 1864. The Union Army under William Tecumseh Sherman consisted of 100,000 men, 254 guns and 35,000 horses. The Confederate Army had 63,000 men and 187 guns. There were about 4,000 reported casualties during the battle. Little of the battle was actually fought on Kennesaw Mountain.
