Therefore, <br />all recorded monitoring events are considered Operational. <br />The monitoring point location for S -5b is located along an unmapped road which is down an un -named gulch which leads into <br />Sheep Corral Gulch. It is located across the draw from Springs 5 and 5a to the west. <br />There is no baseline information collection possible for points initiated after the influence of mining. <br />Figure No. 31 <br />
