5 <br />Artifacts were bagged by level and according to major class such as <br />points, debitage, bone, etc. and returned to the lab for washing and <br />cataloguing. Only artifacts from excavated units were collected. These will <br />be curated at the University of Colorado Museum. <br />Results <br />Initial surface reconnaissance essentially replicated the WCRM survey <br />results. Cultural materials occur in three areas labelled Loci A. B and C <br />(Figure 2). Locus A covers a low interfluvial ridge and a low knoll just down <br />slope of a stock pond. Most of the area has been disturbed, either from stock <br />pond construction or by slope wash. Undisturbed deposits occur on the knoll and <br />in a small pocket between a bladed area and the deep arroyo which bisects the <br />site. Cultural material observed here included a mano and about ten flakes on <br />the margins of the undisturbed ground, most of them in an area covered by low <br />shrubs. <br />Locus H covers a large and completely eroded toe slope to the west of the <br />knoll, and, judging from the quantity of material on the western slope of the <br />knoll, much of the material found in Locus B may derive from erosion of the <br />knoll. WCRM found a mano and a projectile point tip in addition to about 30 <br />flakes. A fragment of the mano was relocated, along with flakes, but the <br />projectile point was not. No testing occurred in Locus B due to its totally <br />eroded nature. <br />Locus C is separated from Loci A and B by deeply incised erosional' <br />channels below the stock pond. It occupies a narrow, sloping bench bordered on <br />the south by an aspen-covered hill slope. Although surface artifacts are low <br />in numbers and the cut bank is devoid of indications of buried materials, the <br />locus was tested. <br />Strati~;raphy <br />The stratigraphic sequence on the site is essentially similar in all loci. <br />Surface soils, varying from about 15 to 50 cm in thickness, consist of a medium- <br />to dark-brown clay loam with a few pebble-sized rocky inclusions. Underlying <br />the surface soils is a massive yellow-brown clay believed to derive from the <br />Pierre shale. In some units, those where burrowing is evident, there is a <br />mottled transition zone (Figure 3), but the topsoil appears to rest <br />disconformally on a much older surface. A level date-from this contact is about <br />1600 BP (see below.) <br />Locus A <br />Twelve shovel probes were dug in Locus A. Of these, five of six probes <br />were positive, including flakes and several pieces of oxidized sandstone. The <br />six probes on the low knoll were sterile. Maximum depth of the positive probes <br />was 40 curbs. <br />To further assess the potential of the shrubby locality, two test units <br />were excavated, each lm x lm square. Test Pit 1 was placed over Positive Probe <br />ST-23. This unit was 30 cm deep, terminating in the massive yellow-brown clay <br />
