Orange you glad you dont have to drink this water?

Our last stop was at douglas falls where we did our second water quality test.  one noticable difference between yellow creek and douglas falls is the color of the rocks, Orange!  This is caused by the chemical reaction of water, air, and pyrite into iron and sulfuric acid which gives the rocks their orange color.  Because of the reaction naturally we found the water to be acidic around 3.8, and no life in the water.  But again we found the overall quality of the water to be moderate.
