An illustration showing what the proposed New World tailings pond would have generally looked like in the drainage where it would have been located—a drainage where melting snowpack and rain pushes through lots of water and saturated the ground in an area prone of earthquakes. Had a breach of the tailing impoundment occurred, the fear was it would send pollution into streams leading to the Clark's Fork of the Yellowstone River. Meanwhile, old mining wastes on nearby Henderson Mountain posed a potential risk of reaching the Lamar River in Yellowstone. Photo courtesy Mike Clark/MSU Library Archives Special Collection
