Photographer Olivier Grunewald puts the spotlight on Cano Cristales (‘River of Five Colors’ or ‘The Liquid Rainbow”) in Sierra de la Macarena, Colombia by taking some breathtaking pictures of the mystical river. At the end of the rainy season in August when the water level drops and the current slows down, the river becomes covered with a red endemic plant called Macarenia Clavigera. Though it may look like the aquatic plant floats freely, it actually grows under the surface where its red stem anchors firmly onto rocks. Another phenomenon lying within the river are the cavernous pits called Los Ochos, which are PreCambrian rocks dating as far back as 1200 million years ago and were carved out by the river itself.
