Creek. However, some ground water may also follow pathways along, or parallel to, <br />the Ross Basin fault (Brenneman vein) and Bonita fault. These pathways would allow <br />for ground-water discharge along a stretch of Cement Creek between the Mogul Mine <br />(on the north) and the Silver Ledge Mine (on the south). <br />A cross section across Cement Creek between the Mogul Mine and Gladstone (near <br />the Red and Bonita Mine) is clearly asymmetrical rather than a classic "V" shape <br />(Figure 10). This asymmetry correlates with the distribution of present and former <br />iron "bogs" and is thought to result from springs depositing mineral precipitates. The <br />build up of precipitates would have gradually forced Cement Creek toward the west. <br />Hence, based upon the local geomorphology ground-water appears to have discharged <br />preferentially along the part of Cement Creek between the Mogul Mine and Gladstone. <br />Furthermore, the discharge appears to have been diffuse rather than concentrated at <br />one spring. <br />If the equilibrium water level in the mine is significantly higher than expected, some <br />portion of the outflow from the flooded mine workings may discharge to Eureka <br />Gulch. The possible discharge to Eureka Gulch would occur via the more generalized <br />fracture permeability which exists at shallow depths where overburden pressure is <br />relatively less (Section 3.2). <br />Gunny\wpltraci\2251 \Mar1993.Rpt <br />49 <br />N:1 SII110AHYbRO-SEARCH <br />
