Now the real wizardry here comes when you strip all the trees away to reveal the archaeological evidence beneath the woodland canopy. They did this by flying over the area in question during the winter, this allows some of the laser beams to penetrate the woodland canopy (won’t work in woods with evergreens) and then they strip out any laser beams that bounce back from the trees but not the ground, really clever stuff. So study this second image to spot the difference and find out what might be there in the woods. |
