16 <br />• RECORDING TECHNIQUES <br />Every site encountered was recorded on an Archaeological Survey of Col- <br />orado Inventory Sheet. Each site record included a description of the site, <br />its environmental setting, a sketch of the site and environs, and direc- <br />tions to the site. The descriptive portion identified the nature of the <br />site, dimensions, types of materials present, and the presence of any <br />features. Also, this part noted in detail the location of the site rela- <br />tive to local topography, hydrological features, and vegetation. <br />Upon discovery of a site, the crew began an intensive examination <br />of the area to determine the limits of the site. Generally, the bound- <br />cries were defined as the point at which no additional cultural materials <br />were observed or where the density became so low as to make it difficult <br />to relate the materials to any central concentration. Once the perimeter <br />was established, a datum was located as close to the center of the site <br />as possible. The crew determined the accurate position of the datum by <br />taking compass bearings of easily identifiable topographic features. This <br />point was marked on the map with the site number and on the ground with a <br />3/8 in. steel bar, on which the site number was stamped. <br />From the datum, transect legs were laid out bisecting the site on <br />its long and short axes and extending from datum to the perimeter. A <br />surveyor's chain was then extended the length of the transect and a swath <br />1 m. wide on either side of the leg was intensively collected. Flakes <br />were collected without recording provenience, other than noting the dis- <br />tance from datum of the first and last occurrence. Flakes were not col- <br />• lected from the rest of the site area unless they were found in concentration. <br />
