D Flock Logic <br />Consulting LLC <br />Memorandum <br />Date: 8 October 2007 <br />To: Collin Stewart <br />Rock l-ogic Consulting <br />PO Box 544 • Cedaredge, CO 81413 <br />Phone: (435) 851-9044 . rocklogicconsulting@gmail.com <br />Brad Lindsay • Consulting Geologist <br />Ry Stone <br />cc: Bill Bear, Roger Pihl, Richard Johnson <br />From: Brad Lindsay <br />Subject: Terror Creek Reservoir Slide Instrument Readings <br />Executive Summa <br />Inclinometers and piezometers at the Terror Creek Reservoir Slide were measured on <br />October 3, 2007. There was very little change since the previous readings in August. Water <br />level in piezometer #2 is lower than it was in July. The rest of the water levels have <br />remained nearly the same. The surface of the slide is mostly dry. There are no apparent <br />0 changes in the cracks within the slope. Vegetation is partially covering the slope. <br />Inclinometers <br />Yeah and Associates installed four inclinometers on the slide area northwest of Terror Creek <br />Reservoir in February 2006. The inclinometers have been labeled TCR-01, TCR-03, TCR- <br />05, and TCR-07. Bowie Resources LLC had previously installed two borings in the slope. <br />They were labeled BL-IOTA and BL-102A. Both of these borings contain a TDR cable and a <br />1" PVC with an inclinometer cable. The cable is crimped above the PVC. The distance from <br />the top of the PVC to the crimp is measured to determine movement. <br />All four TCR inclinometers were measured. Neither of the BL installations was measured. <br />Displacement graphs for the TCR inclinometers have been included with this memorandum. <br />Each graph depicts incremental displacement along the length of the inclinometer casing. <br />There are two graphs for each installation. The graph labeled A-Axis represents movement <br />in the southeast and northwest direction, down slope toward the reservoir. The other graph <br />•
