This is the left half of one of Alexander Gardner's great panorama's taken from the front of the rocks of Devil's Den o/a July 6, 1863. In this foreground are the large rocks that now border the post war Sickles Avenue with the Valley of Death and Little Round Top behind. Notice the fresh grave that has been dug in the rocky ground and Gardner's often seen prop rifle to the left. In my modern view shown in the insert you can see Sickles Avenue and the 4th Maine monument mounted on a large boulder in the background. In the 1863 image this rock has a large bush growing on top or just behind it.
