Airborne LiDAR can penetrate trees and bushes to reveal what lies underneath. LiDAR surveys provide a powerful tool for archaeologists and others to help understand what has happened in a landscape. I was intrigued when I saw a LiDAR image of Gorrick Wood, an area where I have walked extensively, containing several unusual features, so I went exploring to see what I could find 'on the ground'. This talk explains how LiDAR works, how the images are created, and what I managed to discover, including looking at old maps , and evidence of an apparently impossible railway bridge.
