An elderly Wayuu indigenous man in Colombia's arid, far-northern La Guajira department says Pulowi - a female spirit believed to protect lakes and rivers - appeared to him in a dream and told him to "bring harmony" to a stream known as Bruno.

That creek that flows into the Rancheria River was partially diverted to allow for an expansion of the massive Cerrejon open-pit coal mine.
