August 27,2013 C-1992-080/Carbon Junction Mine MLT <br /> Mine. It appears that the bottom of the drainage may have been used for vehicular access at <br /> some point, but the oak brush and other vegetation is beginning to mature, and now prohibits <br /> access by motorized vehicles. <br /> • No changes (headcutting or otherwise) to the Upper Carbon Channel were observed as a <br /> result of the diversion berm's having been breached in 2012. <br /> • The channel at the foot of the reclaimed North Pit slope is well-vegetated, and appears to be <br /> extremely stable. A narrow channel has formed in the floor of the drainage, which likely <br /> carries the normal flows (Photo 5). <br /> REVEGETATION <br /> • The spring and early summer months were dry in Durango,but the area did receive more <br /> than five inches of rainfall in July and August. Vegetation on the reclaimed North Pit slopes, <br /> which are south-facing, appeared somewhat parched (Photo 6),but within the drainages and <br /> on the flatter surfaces, warm season grasses and annual weeds were fluorishing. <br /> • At the location where the temporary diversion berm was breached in 2012, willows were <br /> abundant (Photo 7). It appears that there may be a natural spring at that location, which <br /> provides a more constant source of moisture. <br /> • Within the"natural" Carbon Junction channel, which parallels the "diverted" channel, we <br /> observed a wide variety of desirable vegetation (Photo 8), including: young pinon pine, <br /> young plains cottonwood, box elder, large Indian paintbrush, Rocky Mountain beeplant, and <br /> grasses. <br /> • On the fan of sediment below the erosional gully, vegetation consists almost exclusively of <br /> annual weeds. Numerous large thistle rosettes have appeared in the area disturbed by the <br /> breaching of the berm in 2012. A few solitary Tamarisk plants have become established in <br /> the channel. <br /> Number of Partial Inspection this Fiscal Year: 2 <br /> Number of Complete Inspections this Fiscal Year: 0 Page 3 of 8 <br />
