What does Nessie really look like? Below is an early sighting of the Loch Ness Monster on land, which, to some degree, helps answer the above question.
In 1879, a group of children, apparently at the North shore near a graveyard, observed a strange creature coming down a hillside to Loch Ness. The color of the creature was that of an elephant; gray. It had a small head which was turning from side to side on a long neck. It "waddled" into the water. This sighting was related to Edward Smith by a woman who related it to him as a childhood memory.
