Captured June 5, 2008.Assesses mine site consisting of a large collapsed adit and approximately 500cy of wasterock material adjacent to Granite Creek, with numerous trenches and apparent hydraulic mining. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (59.7 mg/kg) exceeded EPA Region goals. Since the wasterock forms a part of the embankment for Granite Creek, the site has been given a High Priority for further site assessment.2447804 bytesapplication/pdfen-USForest management -- Oregon -- Wallowa-Whitman National ForestHazardous waste site remediation -- Oregon -- Wallowa-Whitman National ForestAbandoned mines -- Oregon -- Wallowa-Whitman National ForestOther
