Movement <br />during the report period was locallyfaster than in recent years, and coincided with <br />historically high water levels in piezometers and stone columns. The report contains <br />recommendations for continued and expanded monitoring, and notes that stabilization <br />designs have been prepared for the power pole above the Material Storage Bench in the <br />Main Surface Facilies area. <br />cc: Kathy Welt, Mountain Coal Company <br />Dan Hernandez, CDRMS <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
