Red river phenomenon has been seen repeatedly – in Canada, China, the US, and in other places of our planet. Rivers, rains, lakes and seas spontaneously turn blood-red, like in the above photo – when abundant rains painted Cameron Falls River red. The phenomenon was captured by a couple of tourists who arrived in the Canadian province of Alberta. Precipitation washed natural pigment of the river in the rocks where the river originates, which gave the water a rich red color. Within two hours, the water flow changed its color.
