Tom Underwood was visiting the Gettysburg Battlefield in 2001 with his family when he recorded this video at Triangular Field. It is considered by many to be perhaps the best, most compelling ghost video ever recorded. It appears to show semi-transparent figures walking through the woods. They seem to be walking uphill, even though the land there is currently flat. It has been noted that the actions of the figures seem to repeat themselves, indicating that this may be a residual haunting -- a kind of recording on the environment. Some think the figures look like soldiers in gray Confederate uniforms.
