¦ <br />Photo 1: Straw bale flow barrier at the crest of the east wall of the North Pit <br />- looking northwest. <br />Visual inspection of the east wall of the North Pit in 2010 indicated that maintenance <br />would be required, as expected, in the two locations where an expression of the <br />Chester Fault system, commonly referred to as the "smile crack" crosses the 10600 <br />bench. The obsequent sense of displacement creates "steps" in the 10,600 bench <br />that require re-grading periodically. Also, depending on the level of snow pack and <br />summer precipitation, every few years one or two small ponds form along the 10,600 <br />bench. During 2010, the single pond that had developed on the 10,600 bench was <br />graded and the bench surface was filled and smoothed to re-establish drainage <br />along the bench. <br />Pitch Reclamation Project <br />Colorado Mined Land <br />Reclamation Board <br />2010 Annual <br />Reclamation Report <br />7 <br />can be accomplished. The area will be closely monitored in 2011. Photographs 1 <br />and 2 show the completed straw barrier.
