CNAPTERTHREE Atfectrld Environment <br />that was surveyed in 1912 for T6S R96W depicts several historic features along the proposed <br />pipeline corridor in the Pazachute Creek Valley (GLO 1912). These include irrigation ditches, <br />buildings, a trail, and the previously described county road. It appeazs that the ti-ai1 is out of the <br />azea of potential effect for the proposed pipeline and that the irrigation ditches and buildings <br />were previously recorded. <br />Segments of new pipeline corridor that ]lave not been previously surveyed would require <br />intensive pedestrian survey for the proposed action. One segment extends southeastwazd from <br />the southeast corner of the lease azea where the proposed pipeline corridor exits the Piceance Site <br />to the Greasewood Compressor Station. The first approximately four miles of tlus corridor <br />follows the floodplain of Hatch Gulch. Previous reseazch in the Piceance Basin has documented <br />the fact that sites aze typically not found along drainages because of the thick vegetative acreage <br />and depositional setting. Since this area along Hatch Gulch is unlikely to result in the discovery <br />of cultural resources by means of survey, the BLM is not requiring a cultural resources inventory <br />of this portion (Belle 1998). <br />Another portion of the proposed pipeline comdor that has not been surveyed is t~etween the <br />south crossing of Piceance Creek and the Pazachute Site. Specifically, all or portions of the <br />corridor in the following sections have not been surveyed: Section 34 T4S R96~N; Sections 2, 3, <br />11, 14, and 24 TSS R96W; and Sections 17, 20, 28, 33, and 34 T6S R96W (Sanfilippo 1998b). <br />These azeas would be surveyed prior to construction. <br />The proposed route for the pipeline route as it drops off of Davis Point into the Parachute Creek <br />Valley has not been surveyed for cultural resources. Portions of this route along Pazachute Creek <br />would be surveyed prior to construction. The portion of this route as it descends the steep face of <br />Davis Point would not require a cultural resources survey. However, the cliffs v.'ould be viewed <br />from a safer location for evidence of mining adits, tunnels, flumes, rock art, shelters, etc. prior to <br />construction. <br />The proposed pipeline corridor crosses a known paleontological locality in Secti~~n 2, T2S R97W <br />(Carpenter 1991). Carpenter concluded that this area has a high potential of fossils, especially <br />vertebrates, being encountered during pipeline construction. In other areas, the surface geology <br />crossed by the proposed pipeline corridor includes the Green River, Uinta, and V1/asatch <br />Formations. All three of these formations aze known to be sources of significant paleontological <br />materials. <br />The proposed pipeline route in the vicinities of Davis Point and further down the: Parachute <br />Creek valley crosses through sections in which Class I paleontological formations have been <br />identified. Specifically, the Green River Formation is known to outcrop in Section 24 TSS <br />R96W and Section 19 TSS R95W, and the Wasatch Formation is known to outcrop in Section 20 <br />T6S R96W (Sanfilippo 1998a). <br />3.11.3.3 Parachute Site <br />Within in the Parachute Creek Valley sites tend to be located above the valley floor. It is thought <br />that the valley floor itself was also utilized in prehistoric times; however little evidence of this <br />occupation is found because of the disturbance from historic farming and ranching.
