It is accessed on foot from the <br />remnants of an old coal exploration road in the mouth of Dove Gulch. It is one of three springs found in this location, originating in the sandstone <br />outcrop and discharges via sheet flow into Dove Gulch. <br />0 <br />Baseline Information for Point S34-22 is derived from events beginning on 6/9/98 through 11/20/03. <br />Point influenced by mining on 11/20/03. <br />Figure No. 79 <br />
