Elevation: 806 feet
Summit: On September 19, 1862, Union troops perched on what was then called Yow Hill showered Confederate soldiers with artillery until the rebels drove them to retreat. More than a quarter of the 7,000 troops who clashed at the Battle of Iuka were killed or wounded. Today, you can drive up a steep gravel road to the quiet, unmarked summit known as "America's bloodiest high point."
