<br />3 <br />3) Preparation of a report presenting data, evaluation, and <br />' findings of Tasks 1 and 2. <br />' 2.3 THE STUDY AREA <br />The CRCC, Martinez Strip is located in southwestern Colorado <br />approximately 20 miles west of Pagosa Springs, Colorado. The <br />project area, consisting of low relief mountains, is Bisected by <br />' Stollsteimer Creek, a perennial meandering stream. The stream <br />has a gradient of 50 feet per mile through the project area with <br />seasonal flows generally between 0.5 and 5 cfs with peak flows <br />exceeding 200 cfs. <br />' Two pit areas are of concern for this report. An active pit, <br /> bounded on the west, north, and east by Stollsteimer Creek and <br />' on the south by Highway 151, encompases the eastern project area <br /> (see Plate 1). Mining in this area will soon be terminated at <br /> which time expansion will proceed to the proposed Barren Ridge <br /> area. <br />The Barren Ridge area, of approximately 15 acres, is bounded on <br />the south and east by Stollsteimer Creek. The north is bounded <br />by a dry channel, and to the west are mountains of increased <br />elevation. Mining within this pit will not proceed to a depth <br />' greater than the projected elevation of Stollsteimer Creek. <br />2.4 GEOLOGY <br />' The local stratigraphy is represented by 4 lithologies defined <br />as recent alluvium, the Kirkland shale, the Fruitland Formation, <br />' and the Pictured Cliffs sandstone.
