Situated in Mauritius, the beautiful natural phenomenon of the coloured earths (scroll to the bottom of the post for a bit of the science behind this force of nature) took me by surprise.
Also known as the seven colours of Chamarel, it’s a must spot to visit. After gazing and photographing the coloured earths for a long while, I took a walk up to the Chamarel Falls. The sight was beautiful.

A bit of science (taken from a board at the Chamarel coloured earths):
This natural phenomenon is due to decomposed basalt gullies. The hot and humid climate helps in the decomposition of the basalt into clay. As a result of total hydrolysis (chemical breakdown of minerals by water), the soluble elements such as salicic acid and cations are washed, leaving a large composition of iron and aluminium which consist of ferralitic soil. The iron sesquioxydes have a red and anthracite colour, whereas the aluminium sesquioxydes have a blue or purplish colour.
