Leviathan Mine, CA

Leviathan Mine, CA
An abandoned sulfur mine in California, just over the state line from Nevada. It's now a Superfund site due to sulfuric acid formed by the oxidizing sulfur. Not only has the acid itself had a deleterious effect on draining into the local streams, but the acidity also leaches metals into solution up to toxic levels. This is a textbook case of "acid mine drainage" from abandoned mines.

God shot and explanation, Steve. The same problem applies at Captains Flat (my recent series).

Thanks, George. I looked at your Captains Flat pix again, and all the metals you mention typically occur as sulfides or associated with them (most commonly pyrite, FeS2). So that's a classic setting for AMD (yeah, it even has an acronym!) AMD also often occurs with coal mines because of associated pyrite. So, yeah, it's a common "mining legacy" issue worldwide!
