Chattanooga is on the south bank of the Tennessee, where that river runs nearly due west. It is at the northern end of a valley five or six miles in width, through which Chattanooga Creek runs. To the east of the valley is Missionary Ridge, rising from five to eight hundred feet above the creek and terminating somewhat abruptly a half mile or more before reaching the Tennessee. On the west of the valley is Lookout Mountain, twenty-two hundred feet above-tide water. Just below the town the Tennessee makes a turn to the south and runs to the base of Lookout Mountain, leaving no level ground between the mountain and river. The Memphis and Charleston Railroad passes this point, where the mountain stands nearly perpendicular. East of Missionary Ridge flows the South Chickamauga River; west of Lookout Mountain is Lookout Creek; and west of that, Raccoon Mountains. Lookout Mountain, at its northern end, rises almost perpendicularly for some distance, then breaks off in a gentle slope of cultivated fields to near the summit, where it ends in a palisade thirty or more feet in height. On the gently sloping ground, between the upper and lower palisades, there is a single farmhouse, which is reached by a wagon-road from the valley east.
