Carol and John Wagner’s ranch is surrounded by green pastures, with spectacular views of the northern San Juan mountains. The Wagners moved here from Pennsylvania in 1986, to raise cattle. When they first arrived, Carol said they wondered what was wrong with the creek that meandered through their property. “Nothing could live in it,” she recalled. Grass didn’t grow along its banks, and there were no fish or bugs. That creek, called Kerber Creek, is just a small piece of the legacy left by hard rock mining across the West. When Tang-colored water spilled from a mine into the Animas River, it caught the nation’s attention. Yet unknown to most, there are people who work day in and day out cleaning up the many hundreds of abandoned mine sites across Colorado. This sort of mine cleanup work is a seldom never-ending process, fraught with logistical challenges, financing problems, even the looming threat of lawsuits.
