3. Surface Topography <br />The topography of the area is formed by the gently northwest dipping beds of the <br />Williams Fork and Iles Formations. These beds are cut by steep, deeply cut <br />drainages. The resulting topography is a series of parallel drainages and gently <br />sloping ridges that are aligned roughly north-south. The ridges are terminated near <br />the south end of the proposed area by east-west trending drainages. <br />Topographic elevations in the proposed area range from about 8300 feet on the <br />high points at the south end of the proposed area to a low of about 6900 feet at the <br />north end of the proposed drilling azea. <br />4. Geology <br />There are two formations potentially exposed in the proposed area. These are the <br />Williams Fork and possibly the Iles Formations of the Mesaverde Group. <br />The Iles Formation is the older and lowermost of the two formations. It consists of <br />massive cliff forming sandstones, siltstones, and coal seams that aze generally thin <br />and often lenticular. A regionally continuous, massive sandstone referred to as the <br />Trout Creek Sandstone Member is located at the top of the Iles Formation. <br />The Williams Fork Formation lies conformably on top of the Iles Formation (Trout <br />Creek Sandstone Member). The formation consists of several series of alternating <br />beds of sandstone, siltstone, shale, and coal. The Williams Fork Formation ranges <br />in thickness from a few hundred feet thick to in excess of one thousand feet in <br />thickness in the proposed exploration area. <br />The coal beds of this formation are present in commercial quantities. Mineable <br />coal thickness ranges from a few feet to tens of feet. Some of the coal seams in <br />this formation are currently mined at the existing Colowyo Mine, east of the <br />proposed areas of drilling. Similar coal seams in this formation are the target for <br />this proposed definition and exploration program. <br />5. Surface Water <br />Surface water drainage systems within the proposed area may include both <br />perennial and ephemeral streams. Perennial streams in the area may include Wilson <br />Creek, Collom Gulch and Straight Gulch. Low average flows on the order of 5-10 <br />gallons per minute are typical for these streams. Significant variation in stream <br />flow is seen on a seasonal basis, and is directly related to precipitation. <br />Ephemeral streams in the proposed exploration area include Taylor Creek, Little <br />Collom Gulch and the East and West Forks of Jubb Creek and the various <br />upstream branches connected to the above-mentioned streams or other drainages. <br />N9CCC ENGUUANIDMG1NO1 DOC106NO006 NOI Texl.doc <br />- - - 1027/0.5 <br />
