northeast and Grand Junction, 57 air miles north. The remoteness of the location is evidenced by <br />the several hours required to reach Nucla by vehicle from the above cities. <br />First Park, amesa-like landform on which the study area is located, is approximately ten miles <br />southwest of the Uncompahgre Plateau. In earliertimes First Park was referred to as Tabequache <br />Park, a sagebrush and pinyon-juniperdominated landscape historically used by the Ute Indians and <br />later by ranchers running livestock on open range. <br />The study area for 1987 and 1999 includes portions of the following sections: <br />Section 6.

This shallow, <br />broad syncline is a simple fold with gently dipping flanks. The Cretaceous-age Dakota sandstone <br />is the youngest formation found in the study area, excepting Quaternary deposits. The Dakota <br />formation consists primarily of resistant yellowish to gray fissile sandstone, and conglomeratic <br />sandstones interbedded with dark gray carbonaceous shales, impure coal, and a basal <br />Revised(9/1999} 2.04.10 - 2 <br />
