A Recipe For Life

We seem to have taken quite a detour last week to get down to this level and the waterfall should be over there somewhere. We’ll follow our ears and get there somehow but first, that looks interesting. There’s probably a correct technical term for these shallow erosions but I just call them cavelets. Let’s climb up and take a look. As you can see from the staining of the rock face, water is leaching minerals from the rocks and if you look up there you can see small stalactites forming. There are also white deposits blooming on the walls which my geologist friends tell me is probably gypsum/selenite. They contain calcium and sulphur so, along with the limestone rocks which contain calcium and carbon, and the water, we have carbon, oxygen, and hydrogen (the basic elements of life) plus at least a couple of others to add to the recipe. We’ll push our way up through these bushes using this tumbling water course as our stairs and see what’s going on.
