The Discovery
Beau Doherty and Tella Osler saw something on the seafloor which did not look like part of the natural ecosystem. The thing had hard edges. It also had a leather strap waving in the current.
A Very Old Camera
Lifting their discovery out of the sand, Beau was astounded to see that it had a round lens. It was very old and sea life and algae had completely encrusted the rusted metal exterior of the thing, but they could still tell that it was a very old camera!
