This is a good place to take a break on a hot day, as the waterfall produces cold wind. DO NOT DRINK this water, It is from an acid mine and the red-orange color comes from iron and rust.

If You need water, don't count on public water fountains in Pittsburgh because they barely ever get turned on.

This is where the Allegheny River and the Monongahela River meat to form the Ohio River.

S THE WATERFALL Demonstrating acid mnine drainage The water here is acid and iron-rich, coming up to the surface from underground mines, stairung the-rocks ruspred. Acid mine drainage (AMID) is a major source of water pollution. Cause of extensive stream environmental damage. The Ocean Coal Company, a subsidiaries of Bevind- White Coal Company Philadelphia, PA, esaiblished several mines in this region including, in 1900, Ocean No. 2. It is purported that drainage from ocean No. 2 is the chief cause of the Red Waterfall Why is it acidic and full of iron? Hundreds of millions of years ago, the massive Pittsburgh Coal Seam formed underneath parts of Pennsylvania, West Virginia, and Ohiờ from ancient swamp plants. Sand, silts, shells, and other -matter were deposited and made a rock seal over the carbon-rich vegetation, This rock contained the mineral "pyrite," made of iron and sulfur Coal mining exposes pyrite to oxygen and ground water causing the formation of sulfuric acid and a number of red, orange, and yellow compound s. AMD occurs when this mine water seeps, or in this-case, bursts out into Streams. The yellow sulfur can be seen in the shale near coal seams.
