Someone once told me about the interesting aspects of Snail Shells in the desert but sadly, I wasn't paying attention - something to do with the thickness of the shell ...
Stick on sand.
Baboon hand-print on dried mud near the Orange River.
Stick in riverbed - the whitish tinge to the sand is caused by abundant chemical salts, sometimes forming large patches of white crystals.
Bushman's Candle - when this plant dies it leaves behind a waxy skeleton which burns like a candle when lit.
I don't know if it was used by the San people but the name implies that it was.
Dead in it's tracks - the ghostly skeleton of a Millipede.
Kilroy was here - A beer can lies where it fell after having been shot, probably quite a few years ago.
The sun-bleached skeleton of a beetle.
Alive, these normally black creatures scurry around the desert - they make me think of Volkswagens.
When it rains these grass patches sprout green and mature quickly to spread their seed.
Another type of desert Snail shell.
