Higher temperatures may be contributing to greater erosion of metals into Rocky Mountain streams, which in turn is causing fish and other wildlife to die.
Zinc and other heavy metals are eroding with increasing frequency and polluting streams in the Rockies. Part of that process is acid rock drainage, where pyrite rocks erode to form sulfuric acid, which in turn frees heavy metals from other rocks.
Several Rocky Mountain waterways have been rendered lifeless by this process.
