3D Pictures!
To see a 3D picture from these stereo pairs, use the "cross-eyed" method.  Position yourself 20 inches from the screen, hold your finger half way to the screen.  Look at your finger and notice that there is a third  image between the other two.  Focus on the center image!
Looking at the Creeper Map, you will see that the AT runs close to the Creeper.  The Appalachian Trail was just behind our campsite. 
You can take 3D pictures using any camera!   Click here to find out how.
