<br /> <br /> <br /> <br /> <br /> <br /> <br />water in this area. Because these paleochannels are generally erratic <br />and of limited lateral continuity, the probability of interception by <br />drilling is low. <br />5.6 Geology <br />5.1 Stratigraphy <br />Most of the exposed rocks belong to the Mesaverde Group of Upper <br />Cretaceous age. Western Fuels has divided the Mesaverde Group in this <br />area into Iles, Lower Williams Fork and Upper Williams Fork Formation <br />equivalents as shown in Figure 5-1. The major coal seams are found in <br />the Lower Williams Fork Formation. The coals are generally associated <br />with siltstones, mudstones and occasional channel sandstones. <br />' S.2 Structure <br />The exploration area is located on the southwest flank of the Red Flash <br />~_ Syncline, an asymmetrical flexure on the northeast flank of the Rangely <br />Anticline. The axis of the syncline trends northwest/southeast and <br />plunges to the southeast towards the much larger synclinal structure of <br />the Piceance Basin. Strike within the area is to the Northwest. Dip <br />within most of the area is approximately 7 degrees to the northeast. <br />As the synclinal axis is approached, dip becomes nearly horizontal. <br />North of the synclinal axis, dip reverses steeply to the southwest, <br />forming the nearly vertically dipping east/west trending hogbacks of <br />Coal Ridge. No faulting is expected in this area. <br />6.0 Proposed Drilling Sites and Access <br />The three proposed hole locations and suggested access routes are shown <br />on Plate I. These sites were chosen to obtain well-spaced geologic <br />data and to minimize environmental damage by avoiding excessive road <br />building. 44CCess to the sites can be accomplished using existing roads <br />a-~.d cross country travel: '17Yilling sites and access routes will be <br />aCcupied, where possible, without the use of a blade (earth moving <br />~}e'ipment). Where required, the use of a blade will be minimized t9 <br />~ittR6~~-surface disturbance. Travel on any of these routes will be <br />restricted or eliminated during and immediately following rain events. <br />The estimated amount of disturbed acreage totals about 1.4 acres. (0.3 <br />acres for drilling/coring sites and 1.1 acres of cross country travel). <br /> <br /> <br /> <br />
