Cameron Falls, in Alberta, Canada : THE PINK WATERFALL

If you venture to Canada's Cameron Falls during the rainy season and you are very lucky, you will see the waters of the falls and river turn the color of Pepto Bismol.  The rare phenomenon is caused when heavy rains and the increased flow of the river picks up silt and takes it downstream.  Normally, this only lasts around two hours.

If a pink waterfall exists, could that mean that unicorns and fairies exist?  I'm not sure I can deal with the repercussions.
