Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />early fall of 2009 when a French drain eras installed to remove water from the upper end of the <br />slide area immediately southeast of the b�rrow site (bare area on the south side of the dam). While <br />no mining activities have occurred, or ale planned, for this area, it remains relatively active and <br />susceptible to reactivation particularly during periods of high precipitation. <br />4.13 Traverse H -H' <br />Traverse H -H (formerly Traverse N -N' ) �eg ms where the Deer Creek drainage meets the Dry Fork <br />Road and continues southward up the Der Creek Road to a locked gate near two stock water tanks <br />fed by a proximal spring (see Map 1 and 2). Two stock ponds (P74 and P93), with earthen <br />embankments, are also located along this traverse. Both ponds are fed by nearby springs. <br />This traverse is located above the projected E -South Mains and the western ends of mined E -seam <br />Longwall Panels E3 and E4, as well as ur�mined E -seam Longwall Panels E5 and E6. Spring 2014 <br />observations found no subsidence related features along this traverse or evidence of diminished <br />spring flow or storage in the stock ponds. <br />4.14 Traverse H' <br />Traverse I -I (formerly Traverse P -P') originates in the Deer Creek drainage adjacent to the lower <br />stock pond (P74) and proceeds eastwards (after swinging considerably north and then south) over <br />mined E -seam Longwall Panels E3 and t4 and a portion of unmined E -seam Longwall Panels E5 <br />(see Maps 1 and 2). E -seam overburden depths along this traverse varies from a low of 450 feet <br />in the Deer Creek drainage to more than 900 feet over E -seam Longwall Panel E5. The soil and <br />colluvium observed along this traverse are relatively stable and are derived from the Wasatch <br />Formation and from intrusive rocks of the West Elk Mountains that overlie consolidated rock units <br />of the Barren Member of the Mesaverde!Formation. <br />Numerous posted MDW pads are accesIsible from this traverse including E3 -6, E3 -12, E3 -17.5, <br />E3 -21, E3 -25, E4 -15, E4 -16, E4 -17 and t4 -18 (see Map 1). Each of these sites was visited during <br />the spring 2014 field activities. In addition, two new MDW pads were under construction over the <br />unmined E -seam Longwall Panel E5 portion of the traverse during our spring 2014 field visit. <br />These pads did not contain MDWs or identification markers (see Map 1). <br />831 - 032.796 Wright Water Engineers, Inc.
