Therefore, all recorded <br />monitoring events are considered Baseline. <br />The monitoring point for SP34-2 is located along an old coal exploration road that runs along the northern facing canyon wall <br />of Dove Gulch. It is part of a system of 6 springs found along this canyon wall. <br />Baseline Information Collection initiated on 10123/97 and not yet considered complete. <br />Point SP34-2 has not been influenced by mining. <br />Figure No. 3
