1.0 Introduction <br />The Tiger Mine Waste Pile, located in the East tributary of Little Frying Pan Gulch <br />(Figure 1), has been identified by the US Bureau of Land Management and Colorado <br />Mountain College (CMC) as a significant contributor of heavy metals. As a result, the US <br />BLM, CMC, and Trout Unlimited (TU) are planning to initiate alarge-scale remedial <br />project to relocate the Tiger Mine Waste Pile and install passive treatment systems within <br />the footprint of the pile. Additionally, hydrologic controls (nut-on/run-off) are to be <br />constructed in the project area to segregate the relocated and existing piles from natural <br />nu7-off It is anticipated that the remedial activities related to the Tiger Mine Waste Pile <br />will result in a significant drop in heavy metals (Cd, Cu, Pb, Mn, Zn) loading into the <br />Lake Fork of the Arkansas River. <br />This report summarizes efforts this summer that are needed to characterize the physical <br />and chemical aspects of the Tiger Mine Waste Pile and soil depth in the proposed <br />location of the repository. The efforts in this report include plowing the access road, <br />drilling of the Tiger Mine Waste Pile, and test pitting in the proposed repository area. <br />Figure 1.
