-9- <br />The site designation system used during the investigation is one em- <br />ployed by all professional archeologists working in the United States. <br />Using site number SMF435 as an example, the first numeral "5" is the number <br />assigned to the state of Colorado. The letters "MF" indicate that the site <br />is located in Moffat County, and the numbers following the county designntion <br />mean that it is the 435th site recorded in Moffat County. A block of unused <br />site numbers was obtained from the Office of the State Archeologist prior <br />to field investigation. The criteria used to determine whether a particular <br />find should be made a site was six flakes in the case of open lithic sites. <br />If fewer than six flakes were found, the find was labelled an "isolated <br />find" or "IF" and numbered consecutively from 1 to n. Thus, IF36 was the <br />36th isolated find made during the investigation. Obviously, site criteria <br />will vary somewhat depending on the situation. Isolated projectile points <br />were also labelled as IFs but if found in association with several flakes <br />or other artifacts, the collection was given a site designation. <br />Sites were described as either open lithic sites, rockshelters or <br />historic sites during the field investigation. The usual practice of des- <br /> <br />cribing sites as chipping stations, campsites, etc. before material from <br />the sites is analyzed was avoided since it is felt that these initial ident- • <br />ifications may bias the analyst. <br />3.3 ANALYTICAL TECHNIQUES <br />After completion of the field investigation, all artifact materials <br />were taken to the University of Colorado, cleaned, numbered, and catalogued. <br />During the catalogueing procedure, the artifacts were divided into relatively <br />broad categories for each site, e.g. projectile points, knives, unifacially <br />and bifacially flaked scrapers, retouched and unretouched flakes, and ground <br />stone implements. The frequencies of artifacts in each category were noted <br />and the type of stone material used in their manufacture was described. <br />Anomalous artifacts were also described. Analysis of pottery was simplified <br />by the fact that only seven potsherds were found. <br />Since the purpose of a cultural resource inventory is to locate and <br />determine the cultural affiliation and general chronological placement of <br />the cultural resources inventoried, detailed artifact analysis is restr9.cted <br />to diagnostic artifacts, primarily projectile points. Ground stone implements, <br />such as manos and metates, are of some diagnostice value in other areas, • <br />
