Aqueous geochemical dynamics of metals and rare earth elements in an acid rock drainage-impacted alpine watershed
Numerous mountain watersheds in the Colorado Mineral Belt (CMB) are impacted by acid rock drainage (ARD) and acid mine drainage (AMD), which mobilize metals and rare earth elements (REEs) into surface waters. In the upper Roaring Fork watershed near Independence Pass, natural ARD from a highly miner
