March 27, 2013 <br />Mr. Jared Ebert <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining, and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Dear Mr. Ebert: <br />RE: Semi - annual Geotechnical Monitoring Report — March 2013 <br />Trapper began submitting semi - annual monitoring reports to the Division, beginning March 2008 with the last <br />report sent on September 27, 2012. Trapper has been monitoring the 2006 landslide area for movement <br />through the use of a continuous monitoring system. <br />Section 3.3.3 of Trapper's permit details the initial configuration of the monitoring system. Currently, there are <br />two sites (site 7 and site 8) that are monitoring the area. A map has been attached showing the location of <br />these sites. Inclinometer, piezometer and surface displacement graphs for both sites covering the time period of <br />September 26, 2012 through March 27, 2013 are attached. During this period, site 7 has shown no significant <br />movement while site 8 has recorded movement. <br />Site 7 is no longer recording any inclinometer or piezometer data. Starting on December 29, 2012 the <br />information that was being sent to the office was being corrupted. This site is located in a remote area and due <br />to the winter weather conditions it was inaccessible. It was thought there might have been a short in the <br />system. Around February 7, 2013 snow had covered the solar panel and the battery was unable to charge up. <br />A blade operator went up to the site to clear off the snow. The snow drifts in the area were deep and the <br />operator accidently drove over the hole with the sensors and severed all the cables. The GPS data is currently <br />being recorded. <br />The data being recorded from the inclinometer and GPS station at site 8 does indicate some movement. There <br />are visible surface cracks in the area. This area is inspected on a regular basis and coned off. Trapper has <br />hired a consultant to analyze what is causing the cracking and movement in this area and to come up with <br />recommendations to prevent or minimize any possible slope failure. The piezometer located by the M seam no <br />longer works. The casing may have been damaged due to the movement. <br />Please contact me if you have any questions. <br />Sincerely, <br />017,10- <br />P.O. Box 187 <br />Tonia Perkins, P.
