A few years ago some professional SCUBA divers decided to explore the waters of Lake George near Hearthstone Campground. Luckily, they had their GoPro running, because they came across the ruins of a small passenger plane, an old car, a memorial stone for Paul Cornell - a gentleman who loved SCUBA diving in that area, and the remains of an old boat. According to the comments, the divers were between 35 and 65 feel below the surface.
The video was taken in 2015 and has almost 25,000 views.
