Reclamation Feasibility Report - Virginia Carron <br />is Boomerang Gulch and the Gilson Gulch turnoff. Access to this mine is by a narrow road starting <br />near the Rattler Tunnel. This mine site was not sampled, but is designated as site #28 on Figure 3. <br />Site #28 is located at LAT. N39° 45' 24.4", LONG. W105° 31' 02.8". The estimated volume of mine <br />waste is 65,000 cubic yards. <br />• <br />Water Quality Impacts <br />The principal water quality effect from this site appears to be from erosion of the mine waste pile. <br />This site was chosen as a high priority because the toe of the waste pile is being eroded by Seaton <br />Gulch and the upper part of the pile is being eroded by an ephemeral drainage off Seaton Mountain. <br />The chemical characteristics of the waste rock are unknown, but a portion of the waste is composed <br />of country rock from the crosscut tunnel. <br />Reclamation Measures <br />The recommended reclamation measure for this site is partial removal and construction of diversion <br />ditches. The portion of the waste rock in Seaton Gulch should be removed and consolidated with <br />the main pile. The removal area will have to be amended with ground limestone and lime before <br />revegetation. Diversion ditches should be constructed to divert upland flow away from the waste <br />pile. One of these diversions should also divert the ephemeral drainage. The site should be <br />investigated in detail before choosing the final reclamation method. <br />• <br />35 <br />Historic Structures <br />The only structure visible at this site is sheet iron sided building that probably housed the <br />compressor and served as the "Dry".
