Observations from the 2009 - 2010 geotechnical monitoring activities indicate that <br />the slope displacement at the east wall of the South Pit is related to movement at <br />major geologic structures, in the style of displacement that has been, and continues <br />to be observed on the east wall of the North Pit. <br />Several actions were taken during 2010 to address the displacement before the <br />onset of winter conditions. An additional 8 survey monuments were installed on the <br />slope by Northstar Surveying, Inc. (Northstar) on October 8, 2010. The monitoring <br />point locations were selected to replace some of the monuments that had been <br />comprised by slope displacement, and to provide a profile of the entire section of the <br />east wall. <br />Pitch Reclamation Project <br />Colorado Mined Land <br />Reclamation Board <br />2010 Annual <br />Reclamation Report <br />8 <br />Photo 2: East Wall of the North Pit erosion repairs.
