Abstract

This study examines the movement of trace elements through the Alamosa River basin, a watershed in southern Colorado with a long history of mining activity. The aims of this research are to : 1) document and explain the vertical and lateral trends of heavy metals in floodplain soils and sediments along the Alamosa River, 2) examine the spatial distribution of metals with distance downstream from the mined area of the watershed, and 3) use the spatial pattern of heavy metals to reconstruct past flood and geomorphic history in the watershed. Heavy metals found below the reservoir may have been released to the watershed and deposited before 1912 during a period of earlier mining activity, or during flooding in 1970 and 1971 when water overtopped the dam. The results of this study suggest the complex fashion in which heavy metals move through the fluvial system
