Title: Cap Martin complex abbreviated preliminary assessment
Author: Wallowa-Whitman National Forest (Agency : U.S.)
Abstract: Assesses site consisting of four collapsed adits, one of which has water discharge, and 6000-80000cy of wasterock materials, most of which is adjacent to Granite Creek. There are numerous trenches and apparent hydraulic mining in the area as well as possible historic dredging operations, with one old log cabin and another apparently collapsed cabin. A Niton XLt unit found that most metals at the site exceeded screening criteria for birds, invertebrates, and plants, but only arsenic (60 to 105.6 mg/kg) exceeded EPA Region goals. The site has been given a High Priority for further assessment.
Description: 21 pp. Tables, appendices, map, illus. "The Site is located approximately 4.5 aerial miles north of Granite, Oregon off County Road 73, then by Forest Service Road 680, which is closed." Captured June 5, 2008.
