Chamarel 7 coloured earth is a strange lava formation in Mauritius. Sunrise is the best time to see the Coloured Earths. Geologists are still intrigued by the rolling dunes of multi-coloured lunar-like landscape. The colours, red, brown, violet, green, blue, purple and yellow never erode in spite of torrential downpours and adverse climatic conditions. The phenomena has never been explained but it is believed the earths are composed of mineral rich volcanic ash.
