<br />t resources inventory was performed on the proposed construction areas by <br />Brad Noisat, representing Science Applications, Inc. of Boulder, Colo- <br />' rado. This work was conducted under the authorization of Federal <br />Antiquities Permit 80-CO-139 and State Antiquities Permit 80-17. This <br />' final report is submitted by Science Applications, Inc. in compliance <br />with the Antiquities Act of 1906, The Historic Preservation Act, 1966, <br />' The National Environmental Policy Act of 1969, Federal Executive Order <br />11593, and the Archaeological and Historic Data Preservation Act of <br />1974. <br />DESCRIPTION OF THE PROJECT AREA <br />' The. project area .is located on south facing ridges and slopes which <br />lie between Thousanc~.Acre Flats, a mesa-like area, and the steep-sided <br />' cliffs and slopes which form the north can}•on wall above the North Fork <br />of the' Gunnison River.. Coal Gulch, an unnamed intermittent drainage <br />' (but known as "A Gulch"), and"Hawksnest Creek, are the principal tribu- <br />taries of the North Fork which drain the slopes in the project area. <br />The project area lies between 6600' and 8100' in elevation. The environmental <br />' context at each of the drill hole locations is given in Table 2. <br />No specific climatic data is available for the immediate project <br />' area. At the Paonia station, the average annual temperature falls <br />between the mid- to high - 40°F. range; annual precipitation averages <br />11" to 13" per year (Kranzush 1977). C limatic condition s. in the area <br />are generally moderate for a mountain valley, although killing frosts <br />' and rapid changes in weather conditions are not uncommon. Agriculture <br />is not possible anywhere in the immediate vicinity. <br />The geology of the area consists of Cretaceous an d. Upper Cretaceous <br />' sandstones and shales (Kranzush 1977). Mountain valley alluvium occurs <br />in the lower areas, <br />No soil survey information is available for this area, but soils in <br />the area are generally non-existent on rocky or cliffy terrain. On more <br />level areas ,accumulations.of.colluvial debris and residual weathering <br />of sandstone and shales -- under the additional influence of biotic <br />' conditions -- have produced soils that are light in color and sandy to <br />loamy in texture. <br /> <br />' 6 <br />
