• temporally or culturally diagnostic artifacts. Prehistoric structural features such as wickiups, tree <br />platforms, eagle traps, etc., can also be evaluated under Criterion A, for their association with <br />events that have made a significant contribution to the broad pattern of our history; and /or under <br />Criterion C, if the structure embodies the distinctive characteristics of a type, period, or method of <br />construction, or that represent the work of a master, or that possess high artistic values, or that <br />represent a significant and distinguishable entity whose components may lack individual <br />distinction. <br />Historic resources may be evaluated under any of the criteria. However, in the absence of <br />structural features or documented association with significant historic events or important <br />contributions of persons significant in history, historical resources are evaluated under essentially <br />the same criteria as prehistoric resources. <br />Anticipated results of the survey were based on the files searches and previous work in the <br />region. Previous inventory of the region suggests a low to moderate probability for encountering <br />cultural resources. Prehistoric /Protohistoric site type expectations in the area are for short-term <br />camps or lithic reduction sites, and aboriginal wooden features. Historic sites were expected to be <br />more prevalent and consisting of trash dumps, short-term hunting camps, or structures related to <br />the ranching industry. Data compiled for the region indicates sporadic prehistoric use of the area <br />rather than long -term habitation; therefore, prehistoric isolated finds were expected to outnumber <br />prehistoric sites. The topography of the project area is defined by a shallow valley bounded by <br />rolling hills in the south and open grassland in the north. The topography is not conducive to <br />long -term or short-term habitation, but extensive slope wash could result in the identification of <br />artifacts from higher locales that are more likely to have been utilized by prehistoric peoples. <br />FIELD METHODS <br />The project area was inventoried using standard pedestrian transects spaced no more than <br />20m apart. Special attention was paid to areas of enhanced subsurface visibility such as road cuts, <br />drainage cut banks, and animal trails for artifacts, features, or buried cultural horizons. A site is <br />defined as a discrete locus of patterned human activity greater than 50 years of age and consisting <br />of five or more prehistoric artifacts with or without features or over 50 historic artifacts with <br />associated features. A single isolated hearth with no other associated artifacts or features will also <br />be recorded as a site. Isolated finds are defined as less than five prehistoric artifacts or 49 historic <br />artifacts without associated features. Exceptions to this definition include: a single core reduction <br />event with a single core and associated reduction debitage; a single pot/bottle drop, where all the <br />sherds are from a single vessel; or prospector pit with/or without artifacts and no associated <br />historic structures or features. These resources will be recorded as isolated finds. Once defined, <br />resources were recorded on OAHP forms. <br />A handheld Garmin 60CSx GPS unit was used to determine site and isolated find locations. <br />All GPS readings were georeferenced to UTM meters and NAD 27 (WAAS corrected to 2 -5 in <br />For Official Use Only: Disclosure of Site Locations Prohibited (43 CFR §7.18) <br />
