A Durango & Silverton train with a K-36 pulling, rounds the curves along the cliffs edge, and above the Animas River near Rockwood, Colorado. Unfortunately, the Animas has an unsavory orange hue to it because of a botched EPA excavating job up near Silverton at the abandoned Gold King Mine. Excavating at the mine caused a "blowout" of wastewater, and released extremely high levels of lead, arsenic, cadmium, beryllium and mercury into Cement Creek, and eventually into the Animas.
