"Does anyone know what causes that brownish flow on the left side the Upper Falls …"
Well, CAL, Oshkosh WI (Cal), kay Moore (Mskatie) and David C Cloutier (Dccloutier) all have it right.
As noted in the Tahquamenon Falls link in Mary's post (I'll betcha a lot of our readers didn't even look there! {wink}):
Quote:"The water is notably brown in color from the tannins leached from the cedar swamps which the river drains. This phenomenon is responsible for the alternative local name 'Root Beer Falls'."
