Negative Results Report Cultural Resource Survey Mountain Coal's Sunset Trail Lease Modifications Permit Revision #PR -15 Gunnison County, Colorado protected places but without associated architecture. Finally, lithic procurement areas must exhibit primary or secondary lithic raw material available on-site, such as nodules eroding from bedrock, lamellar bedrock, or as clasts found in a secondary context (such as alluvial cobbles) at a distance from the primary source. A quarry must exhibit evidence for prehistoric excavation, evidenced by holes dug to access geologic outcrops or gravel sources. Prehistoric artifact terminology follows Adams (2002) for ground stone and Callahan (1979) and Andrefsky (1998) for biface stage, which is determined by calculating width -to -thickness ratio. Historic Period Sites Historic period sites include homesteads, ranching, or agricultural complexes; mining complexes; sites built under federal work programs; timber harvesting; and industry, among other site types. Age criteria is established for potential historic sites by referencing general land office patents, county assessor records, state water division records, historical maps, and 15' USGS maps. Historical dumps and artifact scatters without features are evaluated on a case-by-case basis. A single artifact class within a dump, such as sanitary cans, is recorded as an isolated occurrence; conversely, dumps that exhibit diverse artifact classes and date prior to World War II may be documented as archaeological sites, given their information potential. Linear structures such as water conveyance systems, transmission lines, trails, and roads are documented as sites. An isolated fence line is generally not recorded as a resource unless it demarcates a boundary significant to the history of the area and can be physically linked with a purposeful activity; an isolated fence line may also be documented as a feature of a larger resource. Depending on their cultural context, single or small clusters of mining prospect pits with no associated artifacts are documented as IFs due to their general ubiquity and limited information potential. Criteria for Evaluation Documented cultural resources are evaluated for their eligibility to be listed in the NRHP. NRHP significance criteria are codified under 36 CFR 60.4, summarized below: The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and a) that are associated with events that have made a significant contribution to the broad patterns of our history; or b) that are associated with the lives of persons significant in the past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represents the work of a master, or that possess high artistic value, or that represent a significant or distinguishable entity whose components may lack individual distinction; or d) that have yielded, or are likely to yield, information important in prehistory or history.
