The confluence of a near neutral stream,on the left,with a strongly acidic stream (pH around 3) that drains an oxidizing high-sulfidation epithermal gold deposit in Argentina. The brown color of the acidic stream is caused by precipitates of iron (ferric) hydroxides. The ridge in the distance is the crest of the Andes and the boundary between Argentina and Chile | |
