I took a photo of this unusual sign on a trip to Tasmania. Even in the context of its surroundings, its meaning was far from obvious. A sign warning of low-flying winged people, or abduction by UFO?  Or is that what Tasmanians look like? What do you think?

The general concensus amongst those I spoke to was that the sign warns of …

… deep water!

It is located at the edge of Lake Dulverton, near the small town of Oatlands. The wavy line at shoulder level represents the water surface, and the black bit beneath the person is the bottom of the lake.

What made this non-obvious and something of a curiosity was the absence of any water nearby, the lake having dried up in the vicinity of the sign. Click on the image for the full picture.
