Fall 2015 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mininq Areas <br />3.9 Traverse G -G' <br />Traverse G -G' (previously known as Traverse L -L') originates at Dry Fork Road (Traverse C -C') <br />east of Minnesota Reservoir and follows Horse Gulch Road northward to an intersection that leads <br />either to Apache Rocks (westward) or through a locked gate to the Sylvester Gulch/West Flatiron <br />area (eastward). No changes were observed along this traverse during our fall 2015 field visit. <br />3.10 Photographic Observation Point 4 <br />This location (formerly Photographic Observation Point 7) was established on September 27, <br />2007, at the MCC monitoring station that overlooks Monument Dam and Minnesota Reservoir for <br />reference purposes (see Maps 1 and 2). From this location, various features associated with a large <br />landslide south of the Minnesota Reservoir can be readily identified including the head scarp, <br />hummocky topography, and numerous spring and wetland areas (i.e., discharge locations from the <br />landslide mass). Images from this location have been obtained during each field visit since 2009. <br />Images obtained from the fall 2015 field visit show little discernable difference from those <br />obtained over the last several years and are therefore excluded from this report. <br />3.11 Traverse H -H' <br />Traverse H-1-I'(formerly Traverse N -N') begins where the Deer Creek drainage meets the Dry Fork <br />Road (Traverse C -C') and continues southward up the Deer Creek Road past two stock water tanks <br />(fed by a nearby spring) approximately 0.75 miles to a road intersection (see Map 1 and 2). Two <br />stock ponds (P74 and P93) with earthen embankments are also located along this traverse. Both <br />of these ponds are fed by nearby springs. This traverse is located above the projected E -South <br />Mains and the western ends of mined E -seam Longwall Panels E3, E4, and E5, as well as unmined <br />E -seam Longwall Panel E6. E -seam overburden depths along this traverse range from a low of <br />400 feet near the north end of the traverse to a high of greater than 600 feet at its southern end (see <br />Map 1). <br />Fall 2015 observations along this traverse found subsidence cracks at the turn off to the MVB E5- <br />20 pad access road as well as on the pad, itself. Details associated with the observed subsidence <br />cracks on the MVB E5-20 pad are provided below as Location 2. <br />831-032.797 Wright Water Engineers, Inc. Page 10 <br />March 2016 <br />
