^~oundwater regimes ar,d spr:nss are ~-isibie along the loner ele~•ations, and <br />• the area does not appear t.o be well suited for construction. However, about <br />mid«•ay between the subsoil stockpile and the fan portal is an isolated area of <br />apparent stability. Although the nearby presence of several springs and the <br />creek indicate shallow groundwater, surrounding old Sr gro«~th and the lack <br />of hummocky terrain signify stable ground. This appears to be a Qood site to <br />construct a settling pond. <br />Proceeding ancther 1200 feet south a confluence is encountered where <br />~}•lvester Gulch meets an unnamed drainage, referred to as Drainage A in <br />Figure 1.0. The confluence is broad, relatively flat, and could be construed as <br />being a wetland, althcugh no standing water «°as observed. Construction in <br />• the wetland area ~eould be difficult due to the drainage challenges, especially <br />during spring runoff. <br />3.2 Drainage A <br />East-southeast of the fan portal is a ridge dividing Drainage A and <br />Sylvester Gulch. The ridge appears stable as implied by old fir growth, smooth <br />terrain contours, and a continuous sandstone rock outcrop above. No springs <br />were located around the north face of this ridge. The topography and <br />~ vegetation indicate a good site to construct a portal bench. <br />J <br />4 <br />
