Revegetation is sparse in the topsoiled portion of the West Ridge area, <br />southwest of the West Ridge Road. The non-topsoiled part of the West Ridge area is densely <br />covered with alfalfa. Other vegetation on reclaimed areas included: cicer milkvetch, yellow sweet <br />clover, wheat grasses, mountain brome, sagebrush, and rabbit brush. <br />Weeds. Houndstongue and Oxeye daisy are locally abundant, and need an aggressive control effort. <br />Houndstongue is most abundant next to the 007 flume, and around the two lowermost West Ridge <br />ponds. Oxeye daisy is found in the final Moffat pit area at the entrance gate, at the West Ridge Road <br />"Supercurve", and near the Oak Creek entrance. Thistle is abundant on along the west side of North <br />Road in the Moffat final pit area. Control efforts should be increased here. <br />SLIDES AND DAMAGE <br />A settlement crack in the soil extends a few hundred feet along the west side of North Road in the <br />former highwall area of the final Moffat pit. The crack is about 100 ft. west of the road. The crack is no <br />more than a few inches wide and vertical offset appears to be no more than a few inches.The <br />settlement appears to have occurred prior to the last year's growing season based on old vegetation in <br />the crack. No new settlement is evident. No evidence was found indicating slumping downslope from <br />the crack. The operator's annual monitoring of this reclaimed slope indicates no recent movement. <br />Two gullies extend about 200 feet down a convex, reclaimed hillslope east of North Moffat Road, <br />south of Moffat Downdrain #2. The gullies are less than one foot deep and appear to be stabilizing <br />with vegetative growth. The gullies should be monitored to see whether they further stabilize or they <br />erode. <br />
