In general, an isolated find is defined as 10 or fewer flaked stone artifacts occurring <br />in an area measuring at most 30 meters in maximum dimension. However, when the <br />following conditions are met, the archaeological remains will be recorded <br />as a site: <br />• if three or more of the artifacts present are formal flaked stone tools <br />• if one or more ground stone artifacts (e.g. grinding slabs and manos) are present <br />along with flaked stone artifacts <br />• if ceramic artifacts (commonly pot sherds) are present <br />• if the artifacts are spread out over an area larger than 30 meters in maximum <br /> dimension without a break of more than 30 meters between artifacts <br />More than 10 flaked stone artifacts may be recorded as an isolated find if there is <br />reason to believe that they represent a single episode of flintknapping. For example, a core <br />and 12 waste flakes of the same raw material as the core is to be recorded as an isolated <br />find. One or more completely eroded fire features that are represented by scatters of <br />fire-altered rocks may be recorded as an isolated find. <br />Methods for documentation of material remains of Euro-American activities were <br />also to be recorded as sites or isolated finds. A total of 10 or fewer artifacts occurring in an <br />area measuring 30 meters in maximum dimension are usually be recorded as an isolated <br />find. Locations with features (e.g. fire hearths, dugouts, cabins, corrals, mine shafts, etc.) <br />will generally be recorded as sites. In some cases, recording of one or more features as an <br />isolated find may be justified (e.g. one to several neighboring prospect pits may be <br />documented as an isolated find). <br />A common kind of Euro-American archaeological occurrence in the region is a <br />scatter or concentration of cans, bottles, etc. produced by sheep herders at a location used as <br />a campsite. A sheepherder’s camp may be recorded as an isolated find if there are no <br />archaeological features present and a total of no more than 50 cans, bottles, or other <br />artifacts are present. Sheepherder camps not meeting this definition are recorded as sites. <br />Environmental constraints which might be expected included previous natural <br />ground disturbance that has modified the surface so extensively that the likelihood of <br />finding cultural resources is negligible; human activity within the past 50 years that has <br />created a new land surface such that all traces of cultural resources have been eradicated; <br />natural environmental characteristics that are unfavorable to the presence of historic <br />properties; slopes greater than 30 percent where no potential for rock shelter, rock art, or <br />other cultural properties associated with rock faces or ledges exist; and areas with 100 <br />percent vegetation coverage. <br />All cultural resources that qualified as sites such as prehistoric open camps, lithic <br />scatters, occupied overhangs, rockshelters, and evidence of historic occupation were <br />recorded as they were encountered to standards set by History Colorado’s Office of <br />Archaeology and Historic Preservation. <br />6
